Microsoft has recently released the beta version of TypeScript 5.0 with new decorators standards that allow customizing classes and their members in a reusable manner. It also includes improvements such as more precise type-checking for parameter decorators, const annotations, and a new module resolution option in TS. The beta version aims to simplify, speed up and reduce the size of TypeScript. TypeScript is an open-source programming language developed and maintained by Microsoft, and it targets ECMAScript 2018. To start using the beta version, users can obtain it through NuGet or use the npm command npm install typescript@beta. Future ECMAScript proposals may address the limitations of the new decorators proposal, which is incompatible with --emitDecoratorMetadata and does not support parameter decoration.
