InfoWorld reports that Typescript 5.0 is smaller, faster, and simpler: 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. Decorators can be used on methods, properties, getters, setters, and auto-accessors. Classes can be decorated for subclassing and registration. While TypeScript previously supported experimental decorators, these were modeled on a much older version of the decorators proposal. TypeScript 5.0 will permit decorators to be placed before or after export and export default, a change made since the January 26 beta release of the new version.
