I've checked out the Closure library as instructred, but can't find a way to use the library (i.e. goog.require('math') inside the Console just for trying it out and testing purposes.
Thanks in advance.
Once Closure Library's base.js is loaded, you can reference the library in the Chrome Dev Tools console.
