Microsoft published a beta release of TypeScript 5.0, the company’s strongly typed JavaScript variant, on January 26. The new release aims to modernize decorators for class customization.
Decorators, an upcoming ECMAScript feature, allow for customizing classes and their members in a reusable way, Microsoft noted in a blog post announcing the release. 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.
