 {{{
 #!CommitTicketReference repository="" revision="54804"
 Editor: Improve performance of `WP_Theme_JSON` class by reducing usage of
 expensive array functions.

 In many scenarios array functions are more expensive than using simpler
 `for` or `foreach` loops.

 This changeset results in roughly 4% faster `wp_head` execution time for
 both block themes and classic themes. While this may seem like a small
 win, it is a worthwhile enhancement and only one part of several other
 little performance tweaks which are being worked on to improve performance
 of `theme.json` parsing further.

 Props aristath, desrosj, jrf, spacedmonkey.
 Fixes #56974.
 See #57067.
