What is the scope of variables in scripts?

The scope of a variable refers to the context in which it is defined and accessible. In scripts, variables can have global or local scope.

Can you explain the difference between global and local scope?

Sure! A global variable is accessible from anywhere in the script, while a local variable is only accessible within the function or block where it is defined.

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.

Are there any best practices for using variable scope?

Yes, it's best to limit the use of global variables to avoid conflicts and unintended side effects. Use local variables whenever possible.
