Microsoft Releases Typescript 4.0

August 30, 2020

Microsoft has announced the release of TypeScript 4.0. The latest version of its open-source JavaScript superset. For those unfamiliar with TypeScript, Microsoft’s Daniel Rosenwasser explains it, “If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by adding syntax for static types. The idea is that by writing down the types of your values and where they’re used, you can use TypeScript to type-check your code and tell you about mistakes before you run your code (and even before saving your file).”

TypeScript is one of those tools that you don’t know you need until you don’t have it. I’ll be honest, I’m a bit of a TypeScript newb. So let’s add that to the list of things we could easily talk about on this blog.

And of course Microsoft isn’t done. They already have new features in version 4.1 that you can find in their nightly workshop builds.
