What are common mistakes people make with closures in JavaScript?

One common mistake is not understanding the scope of variables. Closures can lead to unexpected behavior if you're not careful.

Can you give an example of that?

MagicBuddy

Sure! If you create a loop that uses a closure, the variable might not hold the value you expect when the closure is executed.

How can I avoid these mistakes?

MagicBuddy
MagicBuddy

You can avoid these mistakes by using let instead of var in loops, which creates a new scope for each iteration.

Are there any other common pitfalls with closures?

Yes, another pitfall is not returning the closure correctly, which can lead to undefined behavior when you try to access the variable later.
