How can I use map, filter, and reduce together in JavaScript?

Can you explain how to use map, filter, and reduce together in JavaScript?

Sure! You can chain map, filter, and reduce to process arrays efficiently. Do you have a specific example in mind?

Yes, I have an array of numbers and I want to double the even numbers and sum them up.

You can do that like this: const result = numbers.filter(n => n % 2 === 0).map(n => n * 2).reduce((acc, n) => acc + n, 0); This filters even numbers, doubles them, and sums them up.

That makes sense! Can you break down that code for me?

Of course! First, filter selects even numbers, then map doubles each of those, and finally reduce sums them all together.
