Announcing TypeScript 3.8


Today we’re proud to release TypeScript 3.8!

For those unfamiliar with TypeScript, it’s a language that adds syntax for types on top of JavaScript which can be analyzed through a process called static type-checking. This type-checking can tell us about errors like typos and values that are potentially null and undefined before we even run our code. More than just that, that same type analysis can be used to provide a solid editing experience for both TypeScript and JavaScript, powering operations like code completion, find-all-references, quick fixes, and refactorings. In fact, if you’re already using JavaScript in an editor like Visual Studio and Visual Studio Code, your editing experience is really being powered by TypeScript! So if you’re interested in learning more, head over to our website.
