Applies to javascript files inside the platform library folder, the
exposed Engine code, and any javascript files in modules.
Files ending with ".externs.js" will be ignored, you can create a
".eslintignore" file to specify extra files to be ignored.
Until https://github.com/psf/black/pull/1328 makes it in a stable release,
we have to use the latest from Git.
Apply new style fixes done by latest black.
