> TypeScript

I assume this means vscode?

This would seem a weird answer indeed if you don't have context -- which is that VSCode (Microsoft) is developed with native handling of Typescript (Microsoft) -- so is somewhat of the standard in that regard.

The answer is tongue-in-cheek. Basically, don't write JavaScript, write TypeScript and transpile.

The assumption is more weird than the answer. Anyway, I use IntelliJ Ultimate. VsCode only for small scripts
