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
A comparison between the two on-boarding processes. “Adopting Flow & TypeScript” is published by Jamie Kyle.
Or, How I Learned to Stop Worrying & Trust the Compiler When Brendan Eich created the very first version of JavaScript for Netscape Navigator 2.0 in merely ten days, it’s likely that he did not expect how far the Slack Desktop App would take his invention: We use one JavaScript code base to build a multi-threaded desktop application, routinely interacting with native code, targeting Windows, macOS

Most developers understand that JavaScript does not have a notion of datatypes: it’s often referred to as “dynamically typed”, “weakly typed,” or even “untyped.” The distinction is mostly academic, and the bottom line is when you declare a variable, you don’t specify its datatype.

Type Systems for JavaScript Oliver Zeigermann / @DJCordhose http://djcordhose.github.io/flow-vs-typescript/2016_hhjs.html Most recent version including TypeScript 2.0 can be found here (might be work in progress): http://djcordhose.github.io/flow-vs-typescript/flow-typescript-2.html Part I: Introduction Why using type systems? IMHO type systems make code easier to maintain type annotations can mak
The type system is like training wheels. It keeps you from falling, at the price of slowing you down and limiting flexibility.This article is now available in Japanese and Chinese. Last summer we had to convert a huge code base (18,000+ lines of code) from JavaScript to TypeScript. I learned a lot about the strengths and weaknesses of each, and when it makes sense to use one over the other. When i
André Staltz All JS libraries should be authored in TypeScript 16 Mar 2016 I am a JavaScript programmer, and I make some libraries. Recently, however, I’ve been writing TypeScript for RxJS version 5 (used in Angular 2 which is also authored in TypeScript), and I’m in the process of rewriting Cycle.js in TypeScript. Typed vs dynamic is a rather controversial topic, so I’m not trying to spark that d
Updated 7/24 with some spec changes TODO: Add language about string indexers on props types turning off surplus attribute errors Up-front Requirements To use JSX expressions in a TypeScript file, you must use the tsx extension.
