How do scopes affect variable lifetime?

Can you explain how scopes affect variable lifetime in programming?

Sure! In programming, a variable's scope determines where it can be accessed, which directly affects its lifetime.

What happens to a variable when it goes out of scope?

When a variable goes out of scope, it is no longer accessible, and in many languages, it may be garbage collected.

Are there different types of scopes?

Yes, there are generally three types: global scope, local scope, and block scope, each with different lifetimes.

Can you give an example of block scope?

Certainly! In JavaScript, variables declared with 'let' or 'const' inside a block (like an if statement) are only accessible within that block.
