<h1>3 lines of code, that make writing pure JS so much quicker</h1>
<p>Look at the JavaScript tab</p>
<p>PS: Yes, I know it’s easy, but I wanted to have it somewhere for quick copying &amp; pasting.</p>

CSS

body {
    font-family:sans-serif;
    background:#ddd;
    text-shadow:0 2px white;
}

JavaScript

function $(id) { return document.getElementById(id); }
function $t(tag, con) { return (con || document).getElementsByTagName(tag); }
function $$(expr, con) { return (con || document).querySelectorAll(expr); }
