Update JS/TS lexer

[Mesteery]

The JavaScript (and TypeScript lexer) should be updated :

• more errors (Error, EvalError, InternalError, RangeError, ReferenceError, SyntaxError, TypeError, URIError) as Name.Exception ?
• the global object (Name.Builtin, Node.js)
• more Name.Builtin (such as typed arrays, Intl, DataView, Set, Map, WeakSet, WeakMap, Reflect, JSON, ArrayBuffer, Atomics) ?
• highlight \\..., \n, \r, \v, \t, \b, \f, \uXXXX (U+0000 - U+FFFF), \xXX (0x00 - 0xFF) as String.Escape (same as Python lexer)
• **, **=, ??, &&=, ||=, ??= as Operator
• typeof, instanceof, in, void, delete, new as Operator.Word
• missings keywords (function*, yield*), others ?
• use the same base for JavaScript and TypeScript lexers (same operators, ...)
• d regex's flag

What's the rationale for new being Operator.Word?

[Mesteery]

According to MDN and https://tc39.es/ecma262, new is an operator.

[Mesteery]

I also have a question, should the Keyword.Reserved be the same as https://tc39.es/ecma262/#prod-ReservedWord?

[Anteru]

Thanks for the quick reply -- Operator it is. On the second question, yes, that sounds right.

I'm not sure this is the right place to bring it up, so sorry in advance...
I'm looking into replacing the documentation of my site to Mkdocs-material which uses pygments under the hood for syntax highlighting.
The following is how I see it in github, which highlight class names and method names for example:

// Adds a full screen control to the map
map.addControl(new maplibregl.FullscreenControl({container: document.querySelector('body')}));

screen shot in dark mode of github:

This is how it looks in mkdocs material(I hope they are using the latest version of pygment):

This is how it looks in vs code:

Let me know if there's something I can do to help put push this forward.
