Episode Summary

Douglas is a language architect and helped with the development of JavaScript. He started working with JavaScript in 2000. He talks about his journey with the language, including his initial confusion and struggles, which led him to write his book JavaScript: The Good Parts.

Douglas’ take on JavaScript is unique because he not only talks about what he likes, but what he doesn’t like. Charles and Douglas discuss some of the bad parts of JavaScript, many of which were mistakes because the language was designed and released in too little time. Other mistakes were copied intentionally from other languages because people are emotionally attached to the way things “have always been done”, even if there is a better way.

Doug takes a minimalist approach to programming. They talk about his opinions on pairing back the standard library and bringing in what’s needed. Douglas believes that using every feature of the language in everything you make is going to get you into trouble. Charles and Douglas talk about how to identify what parts are useful and what parts are not.

Douglas delves into some of the issues with the ‘this’ variable. He has experimented with getting rid of ‘this’ and found that it made things easier and programs smaller. More pointers on how to do functional programming can be found in his book How JavaScript Works 

Charles and Douglas talk about how he decided which parts were good and bad. Douglas talks about how automatic semicolon insertion and ++ programming are terrible, and his experiments with getting rid of them. He explains the origin of JS Lint. After all, most of our time is not spent coding, it’s spent debugging and maintaining, so there’s no point in optimizing keystrokes.

Douglas talks about his experience on the ECMAScript development committee and developing JavaScript. He believes that the most important features in ES6 were modules and proper tail calls. They discuss whether or not progression or digression is occurring within JavaScript. Douglas disagrees with all the ‘clutter’ that is being added and the prevalent logical fallacy that if more complexity is added in the language then the program will be simpler. 

Charles asks Douglas about his plans for the future. His current priority is the next language. He talks about the things that JavaScript got right, but does not believe that it should not be the last language. He shares how he thinks that languages should progress. There should be a focus on security, and security should be factored into the language. 

Douglas is working on an implementation for a new language he calls Misty. He talks about where he sees Misty being implemented. He talks about his Frontend Masters course on functional programming and other projects he’s working on. The show concludes with Douglas talking about the importance of teaching history in programming.

I was supposed to be in Plymouth yesterday, giving the opening talk at this year’s Future Sync conference. Obviously, that train journey never happened, but the conference did.

The organisers gave us speakers the option of pre-recording our talks, which I jumped on. It meant that I wouldn’t be reliant on a good internet connection at the crucial moment. It also meant that I was available to provide additional context—mostly in the form of a deluge of hyperlinks—in the chat window that accompanied the livestream.

The whole thing went very smoothly indeed. Here’s the video of my talk. It was The Layers Of The Web, which I’ve only given once before, at Beyond Tellerrand Berlin last November (in the Before Times).

As well as answering questions in the chat room, people were also asking questions in Sli.do. But rather than answering those questions there, I was supposed to respond in a social medium of my choosing. I chose my own website, with copies syndicated to Twitter.

Here are those questions and answers…

The first few questions were about last years’s CERN project, which opens the talk:

Based on what you now know from the CERN 2019 WorldWideWeb Rebuild project—what would you have done differently if you had been part of the original 1989 Team?

I responded:

Actually, I think the original WWW project got things mostly right. If anything, I’d correct what came later: cookies and JavaScript—those two technologies (which didn’t exist on the web originally) are the source of tracking & surveillance.

The one thing I wish had been done differently is I wish that JavaScript were a same-origin technology from day one:

https://adactio.com/journal/16099

Next question:

How excited were you when you initially got the call for such an amazing project?

My predictable response:

It was an unbelievable privilege! I was so excited the whole time—I still can hardly believe it really happened!

Later in the presentation, I talked about service workers and progressive web apps. I got a technical question about that:

Is there a limit to the amount of local storage a PWA can use?

I answered:

Great question! Yes, there are limits, but we’re generally talking megabytes here. It varies from browser to browser and depends on the available space on the device.

But files stored using the Cache API are less likely to be deleted than files stored in the browser cache.

More worrying is the announcement from Apple to only store files for a week of browser use:

https://adactio.com/journal/16619

Finally, there was a question about the over-arching theme of the talk…

Great talk, Jeremy. Do you encounter push-back when using the term “Progressive Enhancement”?

My response:

Yes! …And that’s why I never once used the phrase “progressive enhancement” in my talk. ????

There’s a lot of misunderstanding of the term. Rather than correct it, I now avoid it:

https://adactio.com/journal/9195

Instead of using the phrase “progressive enhancement”, I now talk about the benefits and effects of the technique: resilience, universality, etc.
