An example of an AI chatbot conversation about debugging JavaScript scoping issues.
How can I fix scoping issues in my JavaScript code?
Scoping issues in JavaScript often arise from variable declarations. Can you share a snippet of your code?
Sure! I have a function where I'm trying to access a variable defined inside a loop, but it's undefined.
It sounds like you might be facing a closure issue. Could you show me the loop and the function?
Here it is: for (var i = 0; i < 5; i++) { setTimeout(function() { console.log(i); }, 1000); } Why does it log 5 five times?
This happens because var is function-scoped. By the time the timeout executes, i is already 5. You can use let instead.
