How do I debug a map function in JavaScript?
An example of an AI chatbot conversation about debugging a map function in JavaScript.
I'm having trouble with my map function in JavaScript. It doesn't seem to be returning the expected results.
I can help with that! Can you share the code you're using and what results you're expecting?
Sure! Here's my code: const numbers = [1, 2, 3]; const doubled = numbers.map(num => num * 2); console.log(doubled); But it returns undefined.
The code looks correct. Are you sure you're not accidentally modifying the original array or using console.log incorrectly?
Oh, I see! I was trying to log the result of the map function directly without returning it. Thanks!
No problem! Just remember to return the value in the callback function if you're using an arrow function.
