Hello,

is it possible to add an object value from two arrays without changing the other objects in the array? The two arrays should become one array.

Try using concat

> **[Array.prototype.concat() - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/concat)**
>
> The concat() method is used to merge two or more arrays.
> This method does not change the existing arrays, but instead returns a new array.

I created a flow that should help you understand.

Import this flow:

It helps if you copy the payload and paste it for us to use. Then we can test it with your values ...FYI  
 ![Screenshot from 2022-03-14 01-57-54](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/4/34a897e7cd2e3469509a8289b7a700fca1e322a0.jpeg)

This saves us from having to recreate your payload IE: **Create array of arrays of objects**

I know that I can merge two arrays with it. But what I want is something else. I want to add the "purple" values and return the whole thing as one array. I am not interested in the rest of the second array.

Here is the payload:

Possible, but it does not help that your values are strings and contain commas. Something like this should do it.

I totally overlooked the fact that the value is a string. Now the summation of the values works. Small things can be crucial 😉 Thanks for the help!
