Microsoft has announced the release of TypeScript 5.5. TypeScript adds static typing and optional type annotations to JavaScript. It is free and open-source. With its ability to transpile to JavaScript, it is well-suited for building massive apps.

TypeScript 5.5

Today we’re excited to announce the release of TypeScript 5.5!

If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s editor tooling like the auto-completion, code navigation, and refactorings that you might see in editors like Visual Studio and VS Code. In fact, if you write JavaScript in either of those editors, that experience is powered by TypeScript! You can learn more at  the TypeScript website.

To get started using TypeScript through npm with the following command:

npm install -D typescript

or  through NuGet.
