[webkit-dev] Work on new JS language features

[Caio Lima]

Hi WebKittens,

As some of you may know, my colleagues from Igalia have been working
to implement new {Java|ECMA}Script language features in
JavaScriptCore, including BigInt and Class Fields.

We have a number of Class Fields patches awaiting review:

    - Instance Class Fields (https://bugs.webkit.org/show_bug.cgi?id=174212)
      - Private Methods (https://bugs.webkit.org/show_bug.cgi?id=194434)
        - Private Accessors (https://bugs.webkit.org/show_bug.cgi?id=194435)
      - Static Class Fields (https://bugs.webkit.org/show_bug.cgi?id=194095)

And one BigInt patch:
    - BigInt operator "<<" in DFG
(https://bugs.webkit.org/show_bug.cgi?id=192664)

BR,
Caio.
