How does the reduce method work in JavaScript?

Can you explain how the reduce method works in JavaScript?

Sure! The reduce method executes a reducer function on each element of the array, resulting in a single output value.

What does the reducer function look like?

The reducer function takes two parameters: an accumulator and the current value. It processes each element and returns the updated accumulator.

Can you give me an example of using reduce to sum an array of numbers?

Absolutely! Here's a simple example: const sum = numbers.reduce((acc, curr) => acc + curr, 0); This sums all elements in the numbers array.

What if I want to use reduce for an object instead of an array?

You can use reduce with objects by converting the object entries into an array first, then applying reduce to aggregate values.
