How do I debug my JavaScript code using map, filter, and reduce?
An example of an AI chatbot conversation about debugging JavaScript with map, filter, and reduce functions.
I'm having trouble with my JavaScript code that uses map, filter, and reduce. 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 result = array.map(x => x * 2).filter(x => x > 5).reduce((acc, x) => acc + x, 0); But it seems to return an unexpected value.
Let's break it down. First, what does your original array look like?
The array is [1, 2, 3, 4]. I expected the result to be 12.
The issue is in your filter condition. The values after mapping are [2, 4, 6, 8], and only 6 and 8 are greater than 5. So, the reduce will sum those, giving you 14, not 12.
