I tried that but unsuccessfully. Did not get an error but also no grammar for Typescript or C/C++. Perhaps mileage varies with the language.
Edit: I can confirm it works nicely for "javascript". Cool!
I have done typescript successfully. It has another install folder than the default, as the repo has tree-sitter for both tsx and typescript. C/C++ could be a similar situation. The installer should prompt you for it during the setup.
