What are some examples of variable scope in programming?

Can you explain variable scope with some examples?

Sure! Variable scope refers to the accessibility of variables in different parts of your code. For example, a variable declared inside a function is not accessible outside of it.

Can you give me a specific example in JavaScript?

Absolutely! In JavaScript, if you declare a variable using 'let' inside a block, like a loop, it won't be accessible outside that block.

What about global variables?

Global variables are accessible from anywhere in your code. For instance, if you declare a variable outside of any function, it can be used throughout your script.

Are there any best practices for using variable scope?

Yes! It's best to limit the use of global variables to avoid conflicts and to use local variables whenever possible to keep your code modular and maintainable.
