 A very simplistic definition - A closure is a way of accessing a variable outside its scope.

 Ideally, when the getTimer finishes execution, its scope, with local variable tick should also not be accessible. But, it returns 1, 2, 3.. on calling tickTock(). This simply means that, somewhere it keeps a track of the variable tick.

 ## Auto Currying
 Transforming a function that takes multiple arguments into one that if given less than its correct number of arguments returns a function that takes the rest. When the function gets the correct number of arguments it is then evaluated.
