Monaco Editor Playground Code

const value = `a`;

monaco.languages.typescript.typescriptDefaults.setExtraLibs(
[
{content:'declare var a : { b: "aa", c: {d:"e"}} ', filePath:''}
]);

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
	automaticLayout: true,
});

Reproduction Steps

Try the playground, you get no completition for the object 'a'
switch to typescript, and the completition works

Actual (Problematic) Behavior

No codecompletition for global objects in javascript mode

Expected Behavior

code completition should work

Additional Context

No response

A short googling gave me monaco.languages.typescript.javascriptDefaults.setExtraLibs()
Works in your playground, too.

Could you edit your comment in typescript repo so the issue over there is not derailed with helpful comments? Thanks.
