> For packages typed with JSDoc, CTRL/CMD clicking on a function will take you to actual code rather than a type declarations file. I much prefer this experience as a dev. ok i didn't think about this, that's an underrated benefit

could be a customizable behavior in editor/ide though

  There is indeed an option in VSCode "typescript.preferGoToSourceDefinition" -- Prefer Go To Source Definition Makes `Go to Definition` avoid type declaration files when possible by triggering `Go to Source Definition` instead.

This works with Typescript too though?

  It doesn't. You might be thinking of libraries that you wrote, not packages from e.g. npm, which are distributed as JavaScript + type definition files not as TypeScript code.

    It should work if the library was compiled with deceleration map option. Which most libraries are not and it's a shame. It was added like 3 years ago which was probably a bit too late, not even sure why it's not the default. (File size?)

    In real IDEs, not glorified text editors like VSCode, it does. I use this often in IDEA, it's muscle memory so I'm not even completely sure what to press, but it's likely "go to definition" and by default is tied to ctrl+alt+b. IDEA adds its own analysis on top of that provided by the language server. Works on JS + every variant of type definitions I've ever seen, among many other things (not only programming languages, but also database objects, etc).

Its semantics diverge in subtle ways, I believe in both directions (some code that tsserver considers valid IDEA will consider invalid and vice versa).
