How do I debug closure issues in my JavaScript code?

Debugging closure issues often involves checking variable scopes and ensuring that the expected values are retained. Can you share a specific example?

Sure! I have a function that returns another function, but the inner function doesn't seem to access the outer function's variables correctly.

It sounds like you might be facing a common issue with closures. Can you show me the code snippet?

Here it is: function outer() { let x = 10; return function inner() { console.log(x); }; } outer()(); // This logs undefined.

The issue is likely due to how you're invoking the inner function. Make sure you're calling the outer function first to create the closure. Try this: let fn = outer(); fn(); It should log 10.
