It may be confusing to understand how the this keyword is used when accessing a method through the prototype chain. For example if one object has a method with this used and is called through a linked object, what is the context? We’ll play around with this usage and show when context changes.

Isn't Bar function has Foo's context after assigning Foo's prototype to it? So that we basically passing Foo's context (/this) back to Foo in Bar?
