JavaScript - sum array of numbers
0 points
In this article, we would like to show you how to find the sum of an array of numbers using JavaScript.
Quick solution:
xxxxxxxxxx1
const numbers = [1, 2, 3];2
const sum = (accumulator, number) => accumulator + number;3
4
console.log(numbers.reduce(sum)); // 6
In this section, we present an alternative solution for older JavaScript versions.
xxxxxxxxxx1
function add(accumulator, number) {2
return accumulator + number;3
}4
5
var numbers = [1, 2, 3];6
var sum = numbers.reduce(add, 0); // reduce(callbackFunction, initialValue);7
8
console.log(sum); // 6
