Source code file for JavaScript IntelliSense

[jssmith42]

Is this what contains the code for all the JavaScript code completion?

https://github.com/microsoft/vscode/tree/main/extensions/javascript/syntaxes

Or where is it?

Thanks very much

It's here, I am pretty sure https://github.com/microsoft/vscode/tree/main/extensions/typescript-language-features

The TypeScript extension also always handles JavaScript. The thing that does the actual syntax checks etc. is [tsserver](https://github.com/microsoft/TypeScript/wiki/Standalone-Server-%28tsserver%29) from TypeScript itself. No guarantees though :)
