Attachment: Bug 1629106 - Part 1: Implement Logical Assignment Operators proposal. r=yulia!

Restricted to Nightly because there's still an open issue about inferred
function names and because the proposal was only recently moved to stage 3.

Depends on D70821

Hi Christian,
just wanted to give you a heads-up that this bug will add three new compound assignment operators (&&=, ||=, and ??=) to JS. The changes are currently restricted to Nightly builds, because the proposal only just recently reached stage 3.

Thanks,
André

Thanks for the heads-up! I will run the parser target on this for extensive testing once it has landed.

This should be documented here (and also in https://github.com/mdn/browser-compat-data to update the table in the end):
