Closure in JavaScript 🔥

It took some time for me to comprehend, but I believe I have grasped the concept of it.

Essentially, Closure refers to a function bundled together with its lexicon environment, meaning a function with its lexicon scope.

Why is Closure important 🤓?

It allows for inner functions to access another function’s scope.

In JavaScript, functions can be manipulated quite freely.

They can be assigned to a variable.

Passed as a parameter to another function.

And even returned in a function.

Closure can become difficult to understand when a function is returned within a function.

In this scenario, the function retains its lexicon scope and remembers where it was initially present, such as pointing to the value of “a.”

This is an easy example 🫠 but it lays down the fundamentals of Closure in JavaScript.

I do think they should have chosen another name for this concept though 😆.
