I'm a software architect and developer specializing in dynamic programming languages. In the 1980s and 90s I was deeply involved in trying to make Smalltalk an industrial strength programming language. It almost worked. I've been recognized as an ACM Distinguished Engineer and an Ecma International Fellow. I was the editor for the ES5, ES5.1, ES2015.
I became intrigued with them in 6th grade, when small computers filled large rooms.
Its ubiquity. JavaScript is the language of the web and is likely to outlive us all.
In early 2007, I was working as a software architect at Microsoft. At the time, nobody at MSFT cared very much about JavaScript. I saw a need and opportunity to improve JavaScript/ECMAScript for the long term and positioned myself to lead Microsoft's reengagement with TC39.
Producing the ECMAScript 2015 Language Specification and contributing to the design of the language it defines. Part of my role as editor was making sure that all the good ideas actually fit together coherently.
The Realms API and closely-related Secure ECMAScript proposals. These are foundational proposals that enable building secure sandboxing of untested JavaScript code within JavaScript applications.
Impact – knowing that you are having a direct impact of the world's most widely used programming language. You are touching people everywhere.
Throwing out all the good ideas that that would make the language too complex – then trying to make sure that the features you keep play nicely with each other.
Do you think JS is a complex language now? Think what it would be like if hundreds of additional good feature ideas where incorporated into it.
The full history of the language and its standardization efforts. What was the reasoning behind past decisions.
That's why I've spent most of the last two years working on an in depth technical history of the evolution of JavaScript/ECMAScript from 1995 through 2015. It will be completed and available around the middle of 2020.
I hope that TC39 fills in a few key fundamental holes (for example, Realms) and slows down accretion of faddish surface features.
JavaScript is unlikely to ever be the world's best programming language but its role on the web means that it is likely to be one of the world's longest-lived programming languages.
We need to make sure that in 2119 somebody who wants to get a glimpse of what software development was like in the past can open the "2019 JavaScript Advent Calendar" and it will just work!
