How to add script to theme of Wordpress

I want to make my first theme in Wordpress step-by-step but I have problem to insert a script into it.
function loadingScripts(){
wp_register_script( 'awqnimate',
get_template_directory_uri() . '/js/bootstrap.bundle.min.js',
array('jquery'),
'1.1',
'false');
wp_enqueue_script('awqnimate');
}
add_action('wp_enqueue_scripts', 'loadingScripts');
I put this in function.php and in index.php I have <?php get_header(); ?> and <?php footer(); ?> as well and it work perfect. But when I go to my page and check the roots I do not see this scripts at all. Please give me feedback. I read all and cannot see my mistake.
update
I change fill name and something move forwards but...
function loadingScripts(){
wp_register_script( 'awqnimate',
get_template_directory_uri() . '/js/bootstrap.bundle.min.js',
array('jquery'),
'1.1',
'false');
wp_enqueue_script('awqnimate');
}
add_action('wp_enqueue_scripts', 'loadingScripts');
still do not work at all and this work but have some kind of errors Can't find variable: jQuery
wp_register_script
('normwalize', get_template_directory_uri() . '/js/jquery-3.0.0.min.js',
'1.1',
'true');
wp_enqueue_script('normwalize'); ```

File name should be functions.php

you have to change your add_action
add_action('wp_enqueue_scripts', 'awqnimate');

Linking JS/jQuery to WordPress functions.php

Following a tutorial that recommends the following code to link JS/jQuery to WordPress, within functions.php:
<?php
function wpbootstrap_scripts_with_jquery()
{
// Register the script like this for a theme:
wp_register_script( 'custom-script', get_template_directory_uri() . '/bootstrap/bootstrap.min.js', array( 'https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js' ) );
// For either a plugin or a theme, you can then enqueue the script:
wp_enqueue_script( 'custom-script' );
}
add_action( 'wp_enqueue_scripts', 'wpbootstrap_scripts_with_jquery' );
?>
But something is wrong, either the jQuery or the bootstrap.min.js did not link properly, possibly both. How can I ensure that both are linked?

jQuery is not defined in Wordpress, but my script is enqueued properly

I am trying to load a separate javascript file mobile-menu.js to my Wordpress theme. When I look at the console, it says, "jQuery is not defined." However, I know that I enqueued my script files correctly. Any ideas?
HTML file:
<!--this line wasn't here originally-->
<div id="switchmenu"><!--switchmenu begin-->
<?php wp_nav_menu( array( 'theme_location' => 'primary' ) ); ?>
</div><!--switchmenu end-->
functions.php file:
function lapetitefrog_scripts() {
wp_enqueue_style( 'lapetitefrog-style', get_stylesheet_uri() );
wp_enqueue_script( 'lapetitefrog-mobile-menu', get_template_directory_uri() . '/js/mobile-menu.js', array(), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'lapetitefrog_scripts' );
mobile-menu.js file:
jQuery(document).ready(function($) {
$('#menu-icon').click(function() {
$('#switchmenu').slideToggle("fast");
});
});

Add wp_enqueue_script('jquery'); before you enqueue your scripts.

First Make sure that jquery file is include in the header, and your file requied jQuery
wp_enqueue_script(
'lapetitefrog-mobile-menu',
get_template_directory_uri() . '/js/mobile-menu.js',
array('jquery'),
'1.0',
true
);
Second you should start your javascript file like:
(function($) {
$(document).ready(function() {
.......
});
})(jQuery);
OR
// Use jQuery in place of $
jQuery(document).ready(function() {
.....
});

You can try:
enqueue Jquery first.
wp_enqueue_script('jquery');
and then enqueuing the latter script with JQuery dependency in 3rd argument i.e array('jquery') that's what mostly people forget.
wp_enqueue_script( 'lapetitefrog-mobile-menu', get_template_directory_uri() . '/js/mobile-menu.js', array('jquery'), '1.0', true );

Wordpress ships with jQuery by default
// Adds jQuery
add_action('init', 'childoftwentyeleven_down');
function childoftwentyeleven_down() {
// register your script location, dependencies and version
wp_register_script('down',
get_stylesheet_directory_uri() . '/js/down.js',
array('jquery') );
// enqueue the script
wp_enqueue_script('down');
}

The error jQuery is not defined might also appear with jQuery code embedded in your template parts.
This happens when jQuery is added to the footer of the page, while the embedded script tries to execute in the middle of the page.
If this is the case, you need to load jQuery in the header with wp_enqueue_script().
So the last parameter needs to be false here:
wp_enqueue_script( 'my-jquery', get_template_directory_uri() . '/js/jquery.js', array(), time(), false );
Now the code executes in the right order and jQuery will be defined.
Another solution would be to move the embedded script to a Javascript file that will also be added with wp_enqueue_script() to the footer of the page. This is up to you.

how to add jquery to wordpress plugin

This could be a very easy question to wordpress expert. I am a newbie in wordpress and I am having problem using jquery on it. The jquery library is already included because you can see it firebug
I dont know what I am missing here.
This is my code..
add_action( 'wp_enqueue_scripts', array( $this, 'jsscript' ) );
function jsscript() {
?>
<script type="text/javascript">
$(document).ready(function(){
alert('here!');
});
</script>
<?php
}
The jsscript is already on the firebug but it doesn't work. I am getting this error message in firebug.
ReferenceError: $ is not defined
$(document).ready(function(){
I read somewhere that it is not a good idea to include another jquery library and it make sense not to load it again.
I hope somebody can help me.
Thanks in advance.

Instead of just randomly outputting your script you should add it in an external file in your plugin directory, and then include that file with jQuery as a dependency
wp_enqueue_script(
'jsscript',
plugin_dir_path( __FILE__ ) . '/jsscript.js',
array( 'jquery' )
);
The issue you're having now, is that there's no guarantee that the script is outputted after jQuery, in fact there's now guarantee that the script tag you're outputting between the PHP tags is inserted where it's supposed to go at all.

To avoid conflict between other js libraries global $ is not present in wordpress instead use jQuery
Read this for more info
for eg:
jQuery(document).ready(function () {
alert('here!');
});

Put this code your functions.php file
function yourfunction_name() {
global $wp_scripts;
wp_register_script('jqury_lib', "//code.jquery.com/jquery-1.11.2.min.js", array(), null);
}
add_action( 'wp_enqueue_scripts', 'yourfunction_name' );

For theme:
wp_enqueue_script(
'custom-script',
get_stylesheet_directory_uri() . '/js/custom_script.js',
array( 'jquery' )
);
For plugin:
wp_enqueue_script(
'newscript',
plugins_url( '/js/newscript.js' , __FILE__ ),
array( 'scriptaculous' )
);

WP - difficulty with enqueueing scripts

I am trying to add javascript files with wp_enqueue_script. The scripts do not seem to load at all in the page. What I have is::
function uberpasscode_scripts() {
wp_enqueue_script( 'bootstrap', get_template_directory_uri() . "/assets/js/bootstrap.min", array('jquery'));
wp_enqueue_script( 'jquery', get_template_directory_uri() . "/assets/js/jquery-1.11.1.min" );
}
add_action( 'wp_enqueue_scripts', 'uberpasscode_scripts' );

This is because you are missing the javascript (js) extension after .min.
function uberpasscode_scripts() {
wp_enqueue_script( 'bootstrap', get_template_directory_uri() . "/assets/js/bootstrap.min.js", array('jquery'),'', true );
wp_enqueue_script('jquery');
}
add_action( 'wp_enqueue_scripts', 'uberpasscode_scripts' );
Try adding those two parameters. Also, that version of jQuery you are trying to load is too old for bootstrap. Just use the jQuery built into WordPress. Also, make sure that you are putting this into functions.php
If this is still not working, please make sure you have the <?php wp_footer(); ?> function in your footer.php file.
<?php wp_footer(); ?>
</body>
</html>
