What is the `reduce` method in JavaScript?

Description : `reduce` is a method that reduces an array to a single value by iterating over the elements and applying a callback.

Answer :

`reduce` is a powerful method that allows you to reduce an array to a single value by executing a reducer function on each element of the array. The reducer function takes an accumulator and the current value as arguments and returns a new accumulator value. This method is often used for operations like summing all the elements of an array or building an object from an array of data. 

const numbers = [1, 2, 3, 4];

const sum = numbers.reduce((acc, num) => acc + num, 0);
console.log(sum); // 10

const product = numbers.reduce((acc, num) => acc * num, 1);
console.log(product); // 24
