What follows is a list of files that we have detected jQuery-like syntax in, listed in approximate priority order.

Prioritisation was based on the following(rough) criteria:

• is the asset enqueued on the front-end of a site, where performance is most critical?
• how often is the asset rendered, based on rough popularity and how it's implemented?

In eliminating these uses of jQuery, you may find this web site useful: http://youmightnotneedjquery.com/

Files

The following list of files was generated using eslint. Don't forget, once you modify a file, to remove jquery as a dependency wherever that file was enqueued.
