Understanding the JavaScript Closures<\/h2>\n<\/p>\n

What is a closure?<\/strong><\/h3>\n

A closure is an inner function that has access to the outer\/enclosing function\u2019s variables scope chain.
\nClosure has three scope chains i.e.,
\n1) It has access to its own scope (variables defined between its curly brackets)
\n2) It has access to the outer function\u2019s variables, and
\n3) It has access to the global variables.<\/p><\/blockquote>\n

The inner function has access not only to the outer function\u2019s variables, but also to the outer function\u2019s parameters.<\/p>\n

Note that the inner function cannot call the outer function\u2019s arguments\u00a0<\/em>object; however, even though it can call the outer function\u2019s param’s directly.<\/p>\n

In simpler way to say what is closure? If you create\u00a0a function inside \/ within another function\u00a0its called as closure \/ private function.<\/p>\n
