crafting (and) JavaScript

Tagged with #typing

You don't need to rename all your ".js" files to ".ts" to go all in on TypeScript, you can go gradually. Adopt TypeScript step by step, become familiar with it in your existing JavaScript project. No need to put development on hold for weeks, while you convert the code base to TypeScript and fix all type errors. Read on to see how I adopt TypeScript for JavaScript for the sourcecode of jskatas.org.

I am convinced, that stricter types are of help when writing, reading and understanding source code. Why? Ever had the primitive obsession? And if you continue down the (type) rabbit whole, you get to stricter typing. And to Purescript, which attempts "to keep the semantics of JavaScript, while enjoying the syntax and type system of a language like Haskell".
