<p>Last week we finished landing support for the <a
moz-do-not-send="true"
href="https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Nullish_coalescing_operator">nullish
coalescing</a> and <a moz-do-not-send="true"
href="https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Optional_chaining">optional
chaining</a> operators in ESLint and Prettier. The operators are
recent additions to Javascript.</p>
<p>We're still lacking support for globalThis (<a
moz-do-not-send="true"
href="https://bugzilla.mozilla.org/show_bug.cgi?id=1595810">tracking
bug</a>), it looks like this might be in the next major release
of ESLint which is likely to happen in the next couple of months.</p>
<p>If you have questions about ESLint's support, please pop into
#lint:mozilla.org on Matrix. If you find a bug, please file <a
moz-do-not-send="true"
href="https://bugzilla.mozilla.org/enter_bug.cgi?component=Lint%20and%20Formatting&product=Firefox%20Build%20System">it
here</a>.</p>
<p>Thank you to Dave Townsend and Ed Lee on working on incorporating
the support for these new operators.<br>
