I'm trying to figure out the best way return an object found as a key's value, based upon the given unique key...

With this code I get the following error postOwner is not defined. I'm guessing this is because the postOwner: userAccounts.filter(...) call is returning an array with the object as an element.
Instead... I just want to return the object itself, that was found from the entered uniqueKey.
Any idea how to do this?
Edit: made changes in code to match suggestions given in comments below, but still receiving the same error...

That's not how JavaScript and objects work.

Nov 20 '18 at 18:14
Why you're using.filter()at all? With the given exampleuserAccounts.filter(user => user.uniqueKey === x) === userAccounts[x - 1]
– Andreas
Nov 20 '18 at 18:15
Both of the linked questions relate to what you're trying to do. Yes,filterreturns an array; to just get the (first) match, usefind(that's the first question). You can't refer to thepostOwnerproperty on the object in a subsequent property initializer on the same object (that's the second question). (cont'd)
– T.J. Crowder
Nov 20 '18 at 18:18
(continuing) ...so you'll need to have apostOwnervariable prior touserPostswhich is the result of finding the owner, and then use that in youruserPostsinitializer.

With this code I get the following error postOwner is not defined. I'm guessing this is because the postOwner: userAccounts.filter(...) call is returning an array with the object as an element.
Instead... I just want to return the object itself, that was found from the entered uniqueKey.
Any idea how to do this?
Edit: made changes in code to match suggestions given in comments below, but still receiving the same error...

That's not how JavaScript and objects work.

Why you're using.filter()at all? With the given exampleuserAccounts.filter(user => user.uniqueKey === x) === userAccounts[x - 1]

Both of the linked questions relate to what you're trying to do. Yes,filterreturns an array; to just get the (first) match, usefind(that's the first question). You can't refer to thepostOwnerproperty on the object in a subsequent property initializer on the same object (that's the second question). (cont'd)

(continuing) ...so you'll need to have apostOwnervariable prior touserPostswhich is the result of finding the owner, and then use that in youruserPostsinitializer.
