What are global and local scopes in programming?

Can you explain what global and local scopes are in programming?

Sure! In programming, scope refers to the visibility of variables. Global scope means a variable is accessible from anywhere in the code, while local scope means it's only accessible within a specific function or block.

Can you give me an example of each?

Of course! A global variable is declared outside any function, like var globalVar = 10;. A local variable is declared inside a function, like function myFunction() { var localVar = 5; }. Here, localVar can't be accessed outside myFunction.

Why is it important to understand the difference?

Understanding the difference helps prevent naming conflicts and bugs in your code. It also aids in managing memory effectively.
