return false the same as return?

Question

Is

return false 

the same as:

return

Answer 1

Its undefined

console.log((function(){return ;})())

And yes in javaScript return is such a powerful stuff if used nicely in patters. You can return all the way to [] array, {} object to functions too.

Returning "this" you can go ahead and get implementation of class based objects and prototype inheritance and all.
