VSCODE Jump to the JS file definition (not the .d.ts file) [duplicate]

Question

I'm sure thousands of other JS devs are feeling the pain I'm feeling. I love jumping to function definitions in .d.ts files while browsing code in VS Code.

However, sometimes instead of going to the .d.ts file, I'd like to jump to the raw JS code that is being hidden by the .d.ts file that sits in front of it.

Does anyone know how to optionally force a jump to the JS source code (if it exists) and not a TypeScript definition file.

Thanks!

EDIT: I am aware that this has been asked for to the VS Code team and will not be officially supported by them. I'm looking for some sort of hacky workaround (extension or otherwise) to get this to work.

Recently announced, VS Code Insiders (v1.67.2) supports a Go to Source Definition context menu option from right-clicking the symbol. This was committed 19-APR-2022.

This feature requires TypeScript 4.7:

Go To Source Definition

TypeScript 4.7 contains support for a new experimental editor command called Go To Source Definition. It’s similar to Go To Definition, but it never returns results inside declaration files. Instead, it tries to find corresponding implementation files (like .js or .ts files), and find definitions there — even if those files are normally shadowed by .d.ts files.

This comes in handy most often when you need to peek at the implementation of a function you’re importing from a library instead of its type declaration in a .d.ts file.

You can try this new command in the latest versions of Visual Studio Code. Note, though, that this functionality is still in preview, and there are some known limitations. In some cases TypeScript uses heuristics to guess which .js file corresponds to the given result of a definition, so these results might be inaccurate. Visual Studio Code also doesn’t yet indicate whether a result was a guess, but it’s something we’re collaborating on.
