Exciting news! Starting with Visual Studio Code 1.97, they are introducing tree-sitter as an experimental feature.

Tree-Sitter based syntax highlighting for typescript

Since many of our Textmate grammars are no longer maintained, we've been investigating using Tree-Sitter for syntax highlighting. We've started with TypeScript so the team can selfhost it and provide feedback. You can try out an early preview it out with the editor.experimental.preferTreeSitter setting.
