An example of an AI chatbot conversation about common mistakes with closures and callbacks in JavaScript.
What are some common mistakes with closures and callbacks in JavaScript?
One common mistake is not understanding how closures capture variables. This can lead to unexpected behavior.
Can you give me an example of that?
Sure! If you create a loop that uses a closure, it may reference the same variable, leading to all closures using the final value.
How can I avoid this issue?
You can use IIFE (Immediately Invoked Function Expressions) to create a new scope for each iteration of the loop.
Are there any other mistakes I should be aware of?
Yes, another mistake is not handling asynchronous callbacks properly, which can lead to callback hell.
