From eslint.org: Use of the Array constructor to construct a new array is generally discouraged in favour of array literal notation because of the single-argument pitfall and because the Array global may be redefined http://eslint.org/docs/rules/no-array-constructor Hence, we should enable the no-array-constructor across mozilla-central. The rule is already enabled for some areas: https://dxr.mozilla.org/mozilla-central/search?q=no-array-constructor&redirect=false I'm willing to mentor this bug. Approximate steps: - Ensure you've got ESLint setup on mozilla-central (https://developer.mozilla.org/docs/ESLint). - In tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js un-comment the no-array-constructor line. - Remove the no-array-constructor lines from the other .eslintrc.js files (* apart from devtools/ *) - Run: ./mach eslint - Fix the 30 or so instances that it reports as failing. I think all of these should just be switching the `new Array()` to `[]`. - Commit to a patch and push it to mozreview (http://mozilla-version-control-tools.readthedocs.io/en/latest/mozreview.html)

Can I work on this bug as one of my starting bugs ? If so, I'd like to start working unless Dan has already started working. Thanks - Kushal

Hi, Dan has already started working on this (and attached a patch). I'll probably have similar bugs available later today or tomorrow, so keep an eye out if you're looking for more.
