What is variable scope in programming?

Variable scope refers to the accessibility of variables in different parts of your code. It determines where a variable can be used.

Can you explain the difference between local and global scope?

Sure! Local scope means the variable is accessible only within the function or block where it's defined, while global scope means the variable can be accessed from anywhere in the code.

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

If you try to access a local variable outside its scope, you'll get an error indicating that the variable is not defined.

Can you give me an example of variable scope in JavaScript?

Absolutely! In JavaScript, if you declare a variable with 'let' inside a function, it won't be accessible outside that function.
