What is Closure in javascript

Question

Accepted Answer

Closure is a function that has access to its own scope, the outer function's scope, and the global scope.

Closure allows a function to access variables from its outer function even after the outer function has finished executing.
It helps in creating private variables and functions in JavaScript.
Closures are created every time a function is created, and they store references to the variables in their lexical environment.
Example: function outer() { var x = 10; function inner() { console.log(x); } return inner; }
In the above example, the inner function has access to the variable x even after the outer function has returned.

Accepted Answer

A closure is a combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function's scope from an inner function.
