Loading Javascript in WordPress Plugin

If you’re developing a WordPress plugin and wondering how to load Javascript in your plugin, I’ve found an example below.

There is a hook called

<?php
add_action('wp_enqueue_scripts','ava_test_init');

function ava_test_init() {
    wp_enqueue_script( 'ava-test-js', plugins_url( '/js/ava_test_.js', __FILE__ ));
}
