How do I debug closures in JavaScript?

Debugging closures can be tricky. You can use console.log to inspect variables within the closure.

Can you give me an example of a closure?

Sure! Here's a simple example: function makeCounter() { let count = 0; return function() { return count++; }; } This creates a closure that maintains the count variable.

What tools can I use to debug JavaScript code?

You can use browser developer tools, like Chrome DevTools, which allow you to set breakpoints and inspect variables.

Are there any common mistakes to avoid with closures?

Yes, a common mistake is not understanding the scope of variables. Make sure to declare variables with 'let' or 'const' to avoid hoisting issues.
