Let's understand about the concept of WORDPRESS NONCE
=======================================
When creating a WordPress theme or plugin, AJAX is often used in order to enhance the
user experience. In order to ensure security and protect your site against several
types of attacks including CSRF, WordPress provides security tokens called nonces.

What Are WordPress Nonces?
============================

According to the codex, a nonce is a "number used once" to help protect URLs and
forms from certain types of misuse, malicious or otherwise.

WordPress can create nonces for them to be submitted via form or another action, and
on the other hand, it can verify the nonce passed in a form or an action is valid
before accepting the associated data

Functions that we use:
wp_nonce_field
check_ajax_referer,
wp_verify_nonce
