Preparation code

Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries)

Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script>

Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ)

function degSin(deg){ return Math.sin(deg*Math.PI/180); }
function degCos(deg){ return Math.cos(deg*Math.PI/180); }
function degTan(deg){ return Math.tan(deg*Math.PI/180); }
