How do I debug issues with map, filter, and forEach in JavaScript?

I'm having trouble with my JavaScript code using map, filter, and forEach. Can you help me debug it?

Of course! Could you share the specific code snippet that's causing issues?

Sure! Here's my code: const numbers = [1, 2, 3, 4]; const doubled = numbers.map(n => n * 2); const evens = numbers.filter(n => n % 2 === 0); numbers.forEach(n => console.log(n)); But it doesn't seem to work as expected.

I see. The code looks mostly fine, but can you tell me what the expected output is versus what you're actually getting?

I expected to see [2, 4] from the filter, but I'm getting undefined instead.

It sounds like you might be trying to log the result of the filter directly. Make sure to log the variable 'evens' instead of the filter call itself.
