Q:

Google-closure : What's the difference between Goog.provide vs Goog.require

Can anyone tell me the difference. I've just started google-closure. 

A:

goog.provide creates a namespace; goog.require "imports" code from a given namespace so the closure compiler can find it.
Typically when you create a class, you'll provide a namespace for it, and require all of the namespaces that your classes uses directly.
More info (and examples) here: https://developers.google.com/closure/library/docs/tutorial
