How can I fix closure issues in my JavaScript code?

Closure issues often arise when variables are not properly scoped. Can you provide a code snippet where you're facing this problem?

Sure, I have a loop that creates functions, but they all reference the same variable.

This is a common issue. You can solve it by using an IIFE (Immediately Invoked Function Expression) or by using let instead of var in your loop.

Can you show me an example of using IIFE?

Absolutely! Here's a simple example:

for (var i = 0; i < 5; i++) {
    (function(i) {
        setTimeout(function() {
            console.log(i);
        }, 1000);
    })(i);
}

This way, each function gets its own scope.

That makes sense! Thanks for the help!
