How does the scope chain work in JavaScript?

Can you explain how the scope chain works in JavaScript?

Sure! The scope chain in JavaScript is a mechanism that determines the accessibility of variables in nested functions.

What do you mean by accessibility of variables?

Accessibility refers to whether a variable can be accessed from a certain point in the code, based on where it was defined.

How does it handle nested functions?

In nested functions, the inner function has access to the variables of its own scope, the outer function's scope, and the global scope.

Can you give me an example?

Certainly! If you have a variable in an outer function, the inner function can access it, demonstrating the scope chain.
