TypeScript 5.5 introduced the isolated declaration feature, simplifying the process of packaging and distributing JavaScript code. This innovation reduces the time required to create type definition files dramatically.

The JSR registry leverages this feature, making package sharing faster and easier for all developers, regardless of their experience level.
