How do I debug scope issues in my JavaScript code?

Debugging scope issues often involves understanding variable visibility. Can you share a specific example?

I have a variable defined inside a function, but I can't access it outside. Why is that?

That's likely due to function scope. Variables declared inside a function are not accessible outside of it.

How can I make a variable accessible outside the function?

You can declare the variable outside the function or return it from the function and assign it to a global variable.

What about using 'let' and 'const'? Do they behave differently?

Yes, 'let' and 'const' are block-scoped, meaning they are only accessible within the block they are defined in.
