# Sum Up an Array of Numbers

by [kirupa](https://www.kirupa.com/about/whatiskirupa.htm) | filed under [Coding Exercises](https://www.kirupa.com/codingexercises/index.htm)

Here is a fun challenge. We have an array of numbers and want to add them up. Let us say that our array looks as follows:

```js
let numbers = [4, 10, 5, 7, 13, 20];
```

If we had to add these numbers up manually, we would get **59**. We are going to be adding these numbers using JavaScript, and we will show the results is via a web page that will load in our browser. This page won't show anything in the browser, but it will show something when we bring up the [console](https://www.kirupa.com/html5/console.htm):

What the console will show is the result of all of the numbers in our array being summed up. More precisely, it should say `**Sum of array values is: 59**`.
