TypeScript provides native support both for organizing your application's client-side code into a set of modules, and for freeing you from having to manage the resulting script tags.

With TypeScript 5.0, the TypeScript development team has restructured the entire codebase to use ECMAScript modules, reducing package size and improving performance.

Microsoft shipped the beta release of TypeScript 4.7, which tackles a "very difficult feature," ECMAScript Module Support in Node.js.

With TypeScript 2.4 If you've got a module that you only need in special cases, then you can put off loading it until that special case crops up.

TypeScript 5.8 improves interoperability between CommonJS and ECMAScript The new release allows CommonJS modules to be called from ECMAScript and provides a more detailed check of return expressions.
