nodelist2array.js

var nodelist =document.querySelectorAll("div") 

/* THIS - easier to type*/
var nodesArray = [].slice.call( nodelist );

/* OR */
var nodesArray = Array.prototype.slice.call( nodelist )

/* OR THE FASTEST (for Chrome anyway) */
var l = nl.length, arr = new Array( l );
while( l-- ){ arr[l] = nl[l] };
