How to enqueue scripts in my plugin - php

Question

I need to use JavaScript (JQuery) within my plugin. The enqueueing should not be inside the themes' function.php. Imagine telling your users "Please to add this line of code in your functions.php etc..."
/plugins/foo-plugin/foo-plugin.php:
<?php
/**
* Plugin Name: Foo Plugin
* Plugin URI: foobar.com
* Description: ___DEV___
* Version: 1.0.0
*/
if ( ! defined( 'ABSPATH' ) ) exit;
function Foo_Plugin() {
return Foo_Plugin::instance();
} // End Foo_Plugin()
add_action( 'plugins_loaded', 'Foo_Plugin' );
/**
* Load Scrips
*/
function enqueue_js() {
// JS
wp_enqueue_script( 'foo', './assets/js/foo.js', false );
}
add_action('wp_enqueue_scripts', 'enqueue_js');
[...]
I've followed this but I'm not getting my output:
//foo.js:
$(document).ready(function(){
console.log("foo is ready")
})
I have deactivated/reactivated the plugin and nothing. How to use JS/CSS in my plugin? As you've guested, it's my first time creating one ;)
Path to JS:
/plugins/foo-plugin/assets/js/foo.js

In the admin section, use the admin_enqueue_scripts action hook.
function enqueue_js() {
wp_enqueue_script( 'foo', './assets/js/foo.js');
}
add_action('admin_enqueue_scripts', 'enqueue_js');
Also, don't put that false in there. The default should be an empty array if there are no dependencies.
