What is the difference between local and exported variables?

Can you explain the difference between local and exported variables?

Sure! Local variables are defined within a function and can only be accessed there, while exported variables can be accessed outside their defining module.

Why would I use exported variables instead of local ones?

Exported variables allow you to share data between different modules, making your code more modular and reusable.

Can you give me an example of each?

Of course! A local variable might be let x = 10; inside a function, while an exported variable could be export const y = 20; in a module.

What happens if I try to access a local variable outside its function?

If you try to access a local variable outside its function, you'll get a reference error because it's not defined in that scope.
