Summary: Fields in JavaScript (the public fields part of the proposal).
Here's an example:
class C {
x = 2;
}
Currently implemented behind the pref:
javascript.options.experimental.fields
Implementation tracking bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1499448
Pref on-by-default bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1555464
Standard (currently stage 3 proposal):
https://tc39.es/proposal-class-fields/
Platform coverage: all
Target release: 69
Is this feature restricted to secure contexts? No. JavaScript language
features should be enabled everywhere.
Do other browser engines implement this?
Public fields are enabled by default in Chrome 72:

Safari/JSC is in progress (looks like it's not merged yet?):
https://bugs.webkit.org/show_bug.cgi?id=174212
Tests:
Most of our own tests are in
https://searchfox.org/mozilla-central/source/js/src/jit-test/tests/fields
however, they're likely to move to js/src/tests/non262 after the pref has
been turned on by default.
A large number of tests scattered in test262, in js/src/tests/test262.
