What are some examples of using the reduce method in JavaScript?

Can you give me some examples of how to use the reduce method in JavaScript?

Sure! The reduce method is used to execute a reducer function on each element of the array, resulting in a single output value. For example, you can use it to sum up all the numbers in an array.

That sounds interesting! Can you show me a code example for summing numbers?

Absolutely! Here's a simple example:

const numbers = [1, 2, 3, 4, 5];
const sum = numbers.reduce((accumulator, currentValue) => accumulator + currentValue, 0);
console.log(sum); // Output: 15

What if I want to find the maximum number in an array using reduce?

You can do that too! Here's how:

const numbers = [1, 5, 3, 9, 2];
const max = numbers.reduce((accumulator, currentValue) => Math.max(accumulator, currentValue));
console.log(max); // Output: 9
