Javascript Closure is the aggregate of functions clumped together with the references to its surrounding environment. It gives you an outer function’s scope from an internal function. Scopes are contexts of variables. Every object has a link to the scope chain, local first, then parents, and then Global Scope. The Closureallows a function to carry its scope from another context, or we can say another lexical scope.

Javascript Closure

A Closure is the javascript feature that happens. We do not worry about it. Javascript engine creates the Closure, and we have its advantage to use it.
