In this article, we are going to understand the closure concept in javascript.
Closures in JavaScript:
- The closure is inner function that has access to outer function.
- In javascript, closures are created every time a function is created, at function creation time.
- A closure is a function having access to the parent scope, even after the parent function has closed.
Scope:
A scope in javascript defines what variables you have access to.
there are three kinds of scope-
1.Global scope
2.Local scope
3.Outer Function scope.
The closure has three scopes which are as follows:
- It has access to its own scope.
- It has access to its outer function variables.
- It has access to global variables.
