TypeScript LSP

When to choose it

Navigating definitions, references and diagnostics in TS/JS projects.

Choose it if: You work in TypeScript or JavaScript and can install the separate language-server runtime.

Look elsewhere if: You need runtime or end-to-end test results; language diagnostics do not supply them.

What the source describes
