The Continuation-Passing Style in JavaScript
In JavaScript, a callback is a function that is passed as an argument to another function and is invoked with the result when the operation completes. In functional programming, this way of propagating the result is called continuation-passing style (CPS). It simply indicates that a result is propagated by passing it to another function (the callback), instead of directly returning it to the caller.

Practising closures in JavaScript
JavaScript is a very function-oriented language. As we know, functions are first class objects and can be easily assigned to variables, passed as arguments, returned from another function invocation, or stored into data structures. A function can access variable outside of it. But what happens when an outer variable changes? Does a function get the most recent value or the one that existed when the function was created? Also, what happens when a function invoked in another place - does it get access to the outer variables of the new place?
