What are some real-world use cases for JavaScript scope?

JavaScript scope is crucial for managing variable accessibility. For example, in web development, it helps in creating closures for event handlers.

Can you explain closures and how they relate to scope?

Sure! Closures allow a function to access variables from its outer scope even after the outer function has executed. This is useful for data encapsulation.

What about block scope? How does it differ from function scope?

Block scope, introduced with ES6, restricts variable access to the block in which they are defined, unlike function scope which allows access throughout the function.

Can you give an example of using block scope in a loop?

Certainly! Using let in a loop creates a new scope for each iteration, allowing you to maintain separate values for each iteration.
