How to access value in Object?

Question

I have this Array Object that looks like this:

let arr = [
 {Name: "sub", Value: "ababbnnn"}
 ]

I'm trying to access the value of the Name custom:network meaning I want to output this: abcdef1233bfgh. So far I have this loop but I wonder if there may be a cleaner way. Thanks a lot in advance. Here's my code:

You can use the find method:

const value = arr.find(item => item.Name === "custom:network").Value

To cover the case where no item is returned by find, you can use the following approach:

const value = (arr.find(item => item.Name === "custom:network") || {}).Value

Notice that this throws an exception if no object is found. – Bergi Mar 14 '19 at 19:30
@Bergi what would be your approach? – Devmix Mar 14 '19 at 19:30
shouldn't Value's first character be lowercase? – ilia Mar 14 '19 at 19:31

`(arr.find(item => item.Name === "custom:network")||{}).Value` would be my approach here... Since we know it's an array of Objects, if one is found, it's always going to return that, if none are found, it just returns `undefined` – Luca Kiebel Mar 14 '19 at 19:31
