Let’s talk about private variables, or more precisely, defining API methods inside a closure, giving them privileged access to data that code outside the closure cannot see. This is used in several JavaScript design patterns, for example when writing constructors or using the module pattern: The reason people use this pattern, in fact the only reason for doing so as far as I can tell, is encapsulation.
