JSJ 272: Functional Programming and ClojureScript with Eric Normand

JSJ 272: Functional Programming and ClojureScript with Eric Normand

This episode of JavaScript Jabber features panelists Aimee Knight and Charles Max Wood. Special guest Eric Normand is here to talk about functional programming and ClojureScript. Tune in to learn more!

[00:1:14] Introduction to Eric Normand

Eric works for purelyfunctional.tv. The main target market for his company is those people who want to transition into functional programming from their current job. He offers them support, shows them where to find jobs, and gives them the skills they need to do well.

[00:02:22] Address that quickly

Functional programming is used at big companies such as Wal-Mart, Amazon, EBay, Paypal, and banks. They all have Clojure but it is not used at the scale of Java or Ruby.

So yes, people are using it and it is influencing the mainstream programming industry.

[00:3:48] How do you build an application?

A common question Eric gets is, “How do I structure my application?” People are used to using frameworks. Most start from an existing app. People want a process to figure out how to take a set of features and turn it into code. Most that get into functional programming have development experience. The attitude in functional programming is that they do not want a framework. Clojure needs to be more beginner friendly. His talk is a four-step process on how to turn into code.

[00:05:56] Can you expand on that a little?

There are four steps to the process of structuring an application.

  1. Develop a metaphor for what you are trying to do. Developing the first implementation. How would you build it if you didn’t have code?
  2. Develop the operations. What are their properties? Example: will have to sort records chronological.
  3. Develop relationships between the operations.
  4. Run tests and refactor the program. Once you have that, you can write the prototype.

[00:13:13] Why can’t you always make the code better?

Rules can’t be refactored into new concepts. They have to be thrown away and started completely over. The most important step is to think before beginning to write code. It may be the hardest part of the process, but it will make the implementation easier.

[00:17:20] What are your thoughts on when people take it too far and it makes the code harder to read?

He personally has written many bad abstractions. Writing bad things is how you get better as a programmer. The ones that go too far are the ones that don’t have any basis or are making something new up. They are trying to be too big and use no math to back up their code.

[00:20:05] Is the hammock time when you decide if you want to make something abstract or should you wait until you see patterns develop?

He thinks people should think about it before, although always be making experiments that do not touch production.

[00:23:33] Is there a trade off between using ClojureScript and functional JavaScript?

In terms of functional programming in JavaScript don’t have some of the niceties that there are in Clojure script. Clojure Script has a large standard library. JavaScript is not as well polished for functional programming; it is a lot of work to do functional programming it and not as much support.

[00:27:00:] Dave Thomas believes that the future of software is functional programming. Do you agree?

Eric thinks that it seems optimistic. He doesn’t see functional programming take over the world but does think that it has a lot to teach. The main reason to learn functional programming is to have more tools in your toolbox.

[00:31:40] If this is a better way to solve these problems, why aren’t people using it?

There is a prejudice against functional programming. When Eric was first getting into it, people would ask why he was wasting his time. Believes that people are jaded. Functional programming feels foreign because people are used to a familiar way of programming; they usually start with a language and get comfortable.

[00:40:58] If people want to get started with it, is there an easy way in?

Lodash is great to start replacing for loops. It will clean up code. There are other languages that compile to JavaScript. For example, Elm is getting a lot of attention right now. It is a Haskell like syntax. If you want more of a heavyweight language, use TypeScript or PureScript. ClojureScript is into live programming. You are able to type, save, and see results of the code immediately on the screen in front of you.

JSJ 329: Promises, Promise.finally(), and Async/await with Valeri Karpov

Panel:

  • Charles Max Wood
  • AJ O’Neal
  • Aimee Knight

Special Guests: Valeri Karpov 

In this episode, the panel talks with programmer, Valerie Karpov from Miami, Florida. He is quite knowledgeable with many different programs, but today’s episode they talk specifically about Async/Await and Promise Generators. Val is constantly busy through his different endeavors and recently finished his e-book, “Mastering Async/Await.” Check-out Val’s social media profiles through LinkedIn, GitHub, Twitter, and more.

Show Topics:

1:20 – Val has been on previous episodes back in 2013 & 2016.

1:37 – Val’s background. He is very involved with multiple companies. Go checkout his new book!

2:39 – Promises generators. Understand Promises and how things sync with Promises. Val suggests that listeners have an integrated understanding of issues like error handling.

3:57 – Chuck asks a question.

6:25 – Aimee’s asks a question: “Can you speak to why someone would want to use Async/Await?”

8:53 – AJ makes comments.

10:09 – “What makes an Async/Await not functional?” – Val

10:59 – “What’s wrong with Promises or Async/Await that people don’t like it?” - AJ

11:25 – Val states that he doesn’t think there really is anything wrong with these programs it just depends on what you need it for. He thinks that having both gives the user great power.

12:21 – AJ’s background is with Node and the Python among other programs.

12:55 – Implementing Complex Business Logic.

15:50 – Val discusses his new e-book.

17:08 – Question from Aimee.

17:16 – AJ answers question. Promises should have been primitive when it was designed or somewhat event handling.

17:46 – The panel agrees that anything is better than Call Backs.

18:18 – Aimee makes comments about Async/Await.

20:08 – “What are the core principles of your new e-book?” – Chuck

20:17 – There are 4 chapters and Val discusses, in detail, what’s in each chapter.

22:40 – There could be some confusion from JavaScript for someone where this is their first language. Does Async/Await have any affect on the way you program or does anything make it less or more confusing in the background changes?

24:30 – Val answers the before-mentioned question. Async/Await does not have anyway to help with this (data changes in the background).

25:36 – “My procedural code, I know that things won’t change on me because it is procedural code. Is it hard to adjust to that?” – AJ

26:01 – Val answers the question.

26:32 – Building a webserver with Python

27:31 – Aimee asks a question: “Do you think that there are cases in code base, where I would want to use Promises? Not from a user’s perspective, but what our preferences are, but actual performance. Is there a reason why I would want to use both or be consistent across the board?”

28:17 – Val asks for some clarification to Aimee’s question.

29:14 – Aimee: “My own personal preference is consistency. Would I want to use Promises in ‘x’ scenario and/or use Async/Await in another situation?”

32:28 – Val and AJ are discussing and problem solving different situations that these programs

33:05 – “When would you not want to use Async/Await?” – AJ

33:25 – Val goes through the different situations when he would not use Async/Await. 

33:44 – Chuck is curious about other features of Async/Await and asks Val.

36:40 – Facebook’s Regenerator

37:11 – AJ: “Back in the day, people would be really concerned with JavaScript’s performance even with Chrome.” He continues his thoughts on this topic.

38:11 – Val answers the AJ’s question.

39:10 – Duck JS probably won’t include generators.

41:18 – Val: “Have anyone used Engine Script before?” The rest of the panel had never heard of this before.

42:09 – Windows Scripting Host

42:56 – Val used Rhino in the past.

43:40 – Val: “Going back to the web performance question...”

47:08 – “Where do you see using Async/Await the most?” – Chuck

47:55 – Val uses Async/Await for everything on the backend because it has made everything so easy for him.

48:23 – “So this is why you really haven’t used Web Pack?” – AJ

49:20 – Let’s go to Aimee’s Picks!

50:18 – AJ’s story, first, before we get to Promises.

54:44 – Let’s transition to Promises Finally.

54:53 – Val talks about Promises Finally.

JSJ 343: The Power of Progressive Enhancement with Andy Bell

Panel:

  • Charles Max Wood
  • Aimee Knight
  • Chris Ferdinandi
  • AJ O’Neal

Special Guest: Andy Bell

In this episode, the panel talks with Andy Bell who is an independent designer and developer who uses React, Vue, and Node. Today, the panelists and the guest talk about the power of progressive enhancements. Check it out!

Show Topics:

0:00 – Advertisement: KENDO UI

0:34 – Chuck: Hi! Our panel is AJ, Aimee, Chris, myself and my new show is coming out in a few weeks, which is called the DevRev! It helps you with developer’s freedom! I am super excited. Our guest is Andy Bell. Introduce yourself, please.

2:00 – Guest: I am an independent designer and developer out in the U.K.

2:17 – Chuck: You wrote things about Vanilla.js. I am foreshadowing a few things and let’s talk about the power and progressive enhancement.

2:43 – The guest gives us definitions of power and progressive enhancements. He describes how it works.

3:10 – Chuck: I’ve heard that people would turn off JavaScript b/c it was security concern and then your progressive enhancement would make it work w/o JavaScript. I am sure there’s more than that?

3:28 – The guest talks about JavaScript, dependencies, among other things.

4:40 – Chuck: Your post did make that very clear I think. I am thinking I don’t even know where to start with this. Are people using the 6th version? How far back or what are we talking about here?

5:09 – Guest: You can go really far back and make it work w/o CSS.

5:49 – Chris: I am a big advocate of progressive enhancement – the pushback I get these days is that there is a divide; between the broadband era and AOL dialup. Are there compelling reasons why progressive enhancements even matter?

6:48 – Guest.

8:05 – Panel: My family lives out in the boonies. I am aware of 50% of American don’t have fast Internet. People don’t have access to fast browsers but I don’t think they are key metric users.

8:47 – Guest: It totally depends on what you need it for. It doesn’t matter if these people are paying or not.

9:31 – Chris: Assuming I have a commute on the trail and it goes through a spotty section. In a scenario that it’s dependent on the JS...are we talking about 2 different things here?

10:14 – Panelist chimes-in.

10:36 – Chris: I can take advantage of it even if I cannot afford a new machine.

10:55 – Panel: Where would this really matter to you?

11:05 – Chris: I do have a nice new laptop.

11:12 – Chuck: I had to hike up to the hill (near the house) to make a call and the connection was really poor (in OK). It’s not the norm but it can happen.

11:37 – Chris: Or how about the All Trails app when I am on the trail.

11:52 – Guest.

12:40 – Chris: I can remember at the time that the desktop sites it was popular to have...

Chris: Most of those sites were inaccessible to me.

13:17 – Guest.

13:51 – Chuck: First-world countries will have a good connection and it’s not a big deal. If you are thinking though about your customers and where they live? Is that fair? I am thinking that my customers need to be able to access the podcast – what would you suggest? What are the things that you’d make sure is accessible to them.

14:31 – Guest: I like to pick on the minimum viable experience? I think to read the transcript is important than the audio (MP3).

15:47 – Chuck.

15:52 – Guest: It’s a lot easier with Vue b/c you don’t’ have to set aside rendering.

17:13 – AJ: I am thinking: that there is a way to start developing progressively and probably cheaper and easier to the person who is developing. If it saves us a buck and helps then we take action.

17:49 – Guest: It’s much easier if you start that way and if you enhance the feature itself.

18:38 – AJ: Let me ask: what are the situations where I wouldn’t / shouldn’t worry about progressive enhancements?

18:57 – Guest answers the question.

19:42 – AJ: I want people to feel motivated in a place WHERE to start. Something like a blog needs Java for comments.

Hamburger menu is mentioned, too.

20:20 – Guest.

21:05 – Chris: Can we talk about code?

21:16 – Aimee: This is the direction I wanted to go. What do you mean by that – building your applications progressively?

Aimee refers to his blog.

21:44 – Guest.

22:13 – Chuck: I use stock overflow!

22:20 – Guest.

22:24 – Chuck: I mean that’s what Chris uses!

22:33 – Guest (continues).

23:42 – Aimee.

23:54 – Chris.

24:09 – Chris

24:16 – Chris: Andy what do you think about that?

24:22 – Guest: Yes, that’s good.

24:35 – Chris: Where it falls apart is the resistance to progressive enhancements that it means that your approach has to be boring?

25:03 – Guest answers the question.

The guest mentions modern CSS and modern JavaScript are mentioned along with tooling.

25:50 – Chuck: My issue is that when we talk about this (progressive enhancement) lowest common denominator and some user at some level (slow network) and then they can access it. Then the next level (better access) can access it. I start at the bottom and then go up. Then when they say progressive enhancement I get lost. Should I scrap it and then start over or what?

26:57 – Guest: If it’s feasible do it and then set a timeline up.

27:42 – Chuck: You are saying yes do it a layer at a time – but my question is HOW? What parts can I pair back? Are there guidelines to say: do this first and then how to test?

28:18 – Advertisement – Sentry.io

29:20 – Guest: Think about the user flow. What does the user want to do at THIS point? Do you need to work out the actual dependencies?

30:31 – Chuck: Is there a list of those capabilities somewhere? So these users can use it this way and these users can use it that way?

30:50 – Guest answers the question.

31:03 – Guest: You can pick out the big things.

31:30 – Chuck: I am using this feature in the browser...

31:41 – Guest.

31:46 – Chris: I think this differently than you Andy – I’ve stopped caring if a browser supports something new. I am fine using CSS grid and if your browser doesn’t support it then I don’t have a problem with that. I get hung up on, though if this fails can they still get the content? If they have no access to these – what should they be able to do?

Note: “Cutting the Mustard Test” is mentioned.

33:37 – Guest.

33:44 – Chuck: Knowing your users and if it becomes a problem then I will figure it out.

34:00 – Chris: I couldn’t spare the time to make it happen right now b/c I am a one-man shop.

34:20 – Chuck and Chris go back-and-forth.

34:36 –Chris: Check out links below for my product.

34:54 – AJ: A lot of these things are in the name: progressive.

36:20 – Guest.

38:51 – Chris: Say that they haven’t looked at it all before. Do you mind talking about these things and what the heck is a web component?

39:14 – The guest gives us his definition of what a web component is.

40:02 – Chuck: Most recent episode in Angular about web components, but that was a few years ago. See links below for that episode.

40:25 – Aimee.

40:31 – Guest: Yes, it’s a lot like working in Vue and web components. The concepts are very similar.

41:22 – Chris: Can someone please give us an example? A literal slideshow example?

41:45 – Guest answers the question.

45:07 – Chris.

45:12 – Guest: It’s a framework that just happens to use web components and stuff to help.

45:54 – Chuck: Yeah they make it easier (Palmer). Yeah there is a crossover with Palmer team and other teams. I can say that b/c I have talked with people from both teams. Anything else?

46:39 – Chuck: Where do they go to learn more?

46:49 – Guest: Check out the Club! And my Twitter! (See links below.)

47:33 – Chuck: I want to shout-out about DevLifts that has $19 a month to help you with physical goals. Or you can get the premium slot! It’s terrific stuff. Sign-up with DEVCHAT code but there is a limited number of slots and there is a deadline, too. Just try it! They have a podcast, too!

Episode Summary

Brian Lonsdorf works for Salesforce, specializes in functional programming, and wrote a book called Professor Frisby’s Mostly Adequate Guide to Functional Programming. Brian talks about when he got into functional programming and when in their career others should be exposed to it. He talks about the fundamental tenets of functional programming (static mathematical functions), how it differs from object oriented programming, and how to manipulate data in a functional environment. The panel wonders if it is possible to use functional and object oriented programming together and discuss the functional core imperative shell. Brian talks about what is ‘super functional’ and why JavaScript isn’t, but includes methods for making it work. He shares some of the trade-offs he’s found while doing functional programming. Brian defines a monad and goes over some of the common questions he gets about functional programming, such as how to model an app using functional programming.

JSJ 415: Progressive Web Apps with Maximiliano Firtman

Maximiliano Firtman is a mobile web developer from Buenos Ares, Argentina. He has been a developer for 24 years and his most recent focus has been on progressive web apps, or PWAs. Steve and Max reflect on the technologies they were using when they first got started in web development and talk about their experience with mobile development. One area that Max emphasized was bringing the web into the mobile space. They discuss the progression of web access on mobile and some of the available tools. Max notes that responsible design has a very high cost in web performance for mobile devices, which requires unique approaches. They discuss some of the issues with latency in mobile, even on 4G. The solution to this latency is PWAs.

Progressive web apps are a set of best practices to create web apps that are installable. They can work offline at high speeds on several operating systems. Once installed, it looks like any other app on the system. Max delves into more details on how it works. He talks about how the resources for your application are managed. He assures listeners that it’s just a website that’s using a new API, they’re not changing the way the web works, and that when that API is there, the app can be installed. It will also generally use your default browser. Steve and Max discuss how local data is stored with PWAs. To write PWAs, you can use Angular, React, JavaScript, or Vue, and it’s a pretty transparent process. Max talks about some common tools used for local storage and some of the PWAs he’s worked on in the past. The benefit of using PWAs is that they generally run faster than regular web apps. To get started, Max advises listeners to install one and start exploring.

Improvement of Cardiovascular Functional Research After Kidney Transplant

In this issue of JAMA Cardiology, Lim and colleagues report on cardiovascular functional reserve in people with end-stage renal disease before and after kidney transplant. They performed a 3-arm, prospective, concurrent cohort study to assess change in cardiovascular functional reserve after kidney transplant using state-of-the-art cardiopulmonary exercise testing (CPET). They also assessed left ventricular morphologic findings 1 year after transplant. They enrolled 81 participants with stage 5 chronic kidney disease (CKD) who underwent kidney transplant, 85 wait-listed participants with stage 5 CKD who had not undergone transplant, and 87 controls treated for hypertension only. The authors quantified cardiovascular functional reserve using CPET in parallel with transthoracic echocardiography. One year after transplant, a significant improvement in maximum oxygen consumption was found in the transplant group compared with the nontransplant group. Moreover, left ventricular function improved but not the body mass index.

Opportunities & Challenges for Polygenic Risk Scores in Prognostication & Prevention of Cardiovascular Disease

Lowering low-density lipoprotein cholesterol (LDL-C) levels remains a mainstay of cardiovascular disease prevention, but gaps in treatment remain, even in persons with hypercholesterolemia and greatly elevated LDL-C levels. Although well-described gene variants in the apolipoprotein B (APOB), low-density lipoprotein receptor (LDLR), and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes explain small but important fractions of monogenic hypercholesterolemia, recent attention has turned to prognostication of cardiovascular disease using polygenic risk scores (PRS) that incorporate common genetic variants derived from large-scale genome-wide association studies of lipid subfractions. Earlier PRS considered only variants with genome-wide significance, and newer studies have focused on methods that better capture the variance conferred by millions of variants, suggesting an ability to identify risk equivalent to monogenic mutations. There remains a gap in evidence from prospective observational studies or treatment trials regarding the appropriate placement of PRS in risk assessment and lipid treatment decisions relative to information on rare monogenic gene variants, particularly in multiethnic populations.

Disproportionate Emphasis on Proportionate Mitral Regurgitation

Secondary mitral regurgitation (MR) has long been recognized as prognostically important. Even mild MR is associated with adverse outcomes. Yet, surgical trials have not shown improved survival with invasive therapy whereas medical therapy and cardiac resynchronization therapy are associated with improved outcomes. The 2018 publication of the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) and Multicentre Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients With Severe Secondary Mitral Regurgitation (MITRA-FR) trials and their apparently discordant results have focused attention on the differences in trial design as well as patient populations.
