/**
|
|
* Thin jQuery.ajax wrapper for WP REST API requests.
|
|
*
|
|
* Currently only applies to requests that do not use the `wp-api.js` Backbone
|
|
* client library, though this may change. Serves several purposes:
|
|
*
|
|
* - Allows overriding these requests as needed by customized WP installations.
|
|
* - Sends the REST API nonce as a request header.
|
|
* - Allows specifying only an endpoint namespace/path instead of a full URL.
|
|
*
|
|
* @since 4.9.0
