TypeScript 5.0, an update to Microsoft’s strongly typed JavaScript variant, is now available as a production release, Microsoft announced March 16. With the upgrade, TypeScript has been rebuilt to use ECMAScript modules. TypeScript 5.0 also modernizes decorators for class customization.
ECMAScript modules reduce package size and boost performance. Decorators, an upcoming ECMAScript feature, allow for customizing classes and their members in a reusable way, Microsoft noted in a March 1 blog post.
