TypeScript 5 introduced a new bundler module option, named --moduleResolution bundler aimed to improve coexistence with modern bundlers like Vite, esbuild, swc, Webpack, Parcel, and others.

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.
