Intro: About ClosuresWhat is a closure?from a definition point of view, all functions can be closures. A closure is formed when a function invokes a variable (usually called a free variable) that is not defined within its own scope, and the closure is a combination of the code block and the data in the context in which the code block was created .Example: function mytest () {var test=10;return function () {test++;alert (test); }}var atest = new MyTest
