NodeList to Array

NodeListToArray.js

// create array from NodeList without modifying NodeList Prototype
var arr = Array.prototype.slice.call( document.querySelectorAll('div') );

// extend NodeList prototype...
NodeList.prototype.array = function() {
  return Array.prototype.slice.call(this);  
};
// ...and use it as chained method
var arr = document.querySelectorAll('div').array();

// now we can use forEach
arr.forEach(function(e,i){ 
  console.log(e) 
});
