What is scope in JavaScript?

What is scope in JavaScript?

Scope in JavaScript refers to the accessibility of variables, functions, and objects in some particular part of your code during runtime.

Can you explain the difference between global and local scope?

Global scope means variables are accessible from anywhere in the code, while local scope means they are only accessible within the function they are defined.

What happens if I try to access a local variable outside its function?

If you try to access a local variable outside its function, you'll get a reference error because the variable is not defined in that scope.

Are there any exceptions to these rules?

Yes, closures can create exceptions by allowing inner functions to access variables from their outer function's scope.
