This is an ongoing list of my most-used WordPress snippets for functions.php files. Take the meat, spit out the bones! The eating references in these descriptions are mounting.

wordpress-functions-template.php

<?php



/* Updates jQuery manually */

function update_jquery() {
	if (!is_admin()) {
		wp_deregister_script("jquery");
		wp_register_script("jquery", "http://code.jquery.com/jquery.js", false, "11.11.1");
		wp_enqueue_script("jquery");
	}
}
add_action("init", "update_jquery");



/* Adds custom scripts to the page */

function my_scripts() {
	if ( !is_admin() ) {	
		global $wp_styles;
		wp_enqueue_style("bootstrap", "http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css");
		wp_enqueue_style("font-awesome", "http://maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css");
		wp_enqueue_style("style", get_template_directory_uri() . "/style.css");
		wp_enqueue_script("bootstrap", "http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js", array("jquery"));
		wp_enqueue_script("html5shiv", "https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js");
		$wp_styles->add_data("html5shiv", "conditional", "lt IE 9");
		wp_enqueue_script("respond", "https://oss.maxcdn.com/respond/1.4.2/respond.min.js");
		$wp_styles->add_data("respond", "conditional", "lt IE 9");
		wp_enqueue_script("script", get_template_directory_uri() ."/js/default.js", array("jquery"));
	}
}
add_action("wp_enqueue_scripts", "my_scripts");



?>

for some reason the conditionals don't seem to work for me in WP 3.8
scripts just get included in head without the conditional tags ;(

wp_enqueue_script( $handle, $src, $deps, $ver, $in_footer );

2 pointers:

1. Maybe you should put "what you can" in the footer?
2. Maybe adding versions for enqueues? (because of caching issues if you upgrade script versions)
