Why coroutines won’t work on the web
The topic of coroutines (or fibers, or continuations) for JavaScript comes up from time to time, so I figured I’d write down my thoughts on the matter. I admit to having a soft spot for crazy control-flow features like continuations, but they’re unlikely ever to make it into ECMAScript. With good reason. The big justification for coroutines in JavaScript is non-blocking I/O. As we all know, asynch

JavaScript for People Who Hate JavaScript
I have a long history with JavaScript, dating back to the glory days of the most perfect technology ever to have graced computers: DHTML. DHTML was totally rad, like how the Budweiser frogs were rad. In the late 90’s you really couldn’t do much of anything on the web except add 88x31 buttons and build with 1x1.gif spacer tricks. But then Dynamic HTML came out in IE4 and a whole world of hover anim
ES proposal: `Promise.try()`
Update 2017-08-12: I added an FAQ. The proposal “Promise.try()” by Jordan Harband is currently at stage 1. This blog post explains how it works.

GitHub - globalizejs/globalize: A JavaScript library for internationalization and localization that leverages the official Unicode CLDR JSON data
Each language, and the countries that speak that language, have different expectations when it comes to how numbers (including currency and percentages) and dates should appear. Obviously, each language has different names for the days of the week and the months of the year. But they also have different expectations for the structure of dates, such as what order the day, month and year are in. In
Why We Chose Typescript - Upvoted
Niranjan Ramadas (u/nr4madas) Engineering Manager Earlier this year, our CEO, Steve, mentioned we are redesigning the site. Great! But how? Frontend engineering is in a very different state than it was when Reddit was first conceived. We have a large depth of options for just about every layer of web app development. From how to render views, style content, serve assets, and write code, frontend d
