title: ECMAScript 5 compatibility script for older browsers
body: <p>Is there already a opensource project out there which implements ECMAScript 5 features for browsers which do no implement it natively? Something like the <a href="http://code.google.com/p/ie7-js/" rel="noreferrer">IE7.js</a> project which implements missing standard stuff in Internet Explorer.</p>
  
  <p>I'd like to use the new Function.bind() and String.trim() and JSON.parse() functions but they are currently only available in the newest browsers like the latest Chromium. I'd like to simply include a script like "ecma5.js" which then implements all this stuff if missing in the browser.</p>
  
  <p>So is there already a project like this available? If not then I have to do it myself.</p>
