TypeScript's Find All References and other requests are slow when used in this repository

For some reason TypeScript has been taking much more time when responding to requests such as Find All References.

My current guess is that this is due to [email protected] itself being slow, maybe upgrading to @4 will fix it?

@paul-marechal I just tested it by switching between the built-in vscode version of TypeScript and the one used in the project. Running Find All References with @4.4.3 takes 12 seconds, compared to @3.9.10 which takes 75 seconds.

Thanks for the benchmark! I opened a PR to update the TypeScript version we use to build as this is the one we usually recommend people to use for code assistance. Or is it just fine to tell people to use this version bundled with VS Code?

I'd prefer the former, personnally.
