I am creating a website. I am trying to add a "Warn" feature, but when I store the warn into a user, I get this: 0: 1

Here is what I mean by 0: 1 So, here is my code... The variable that is causing this problem is newUser[0].warn = newWarn

const newMsg = {
        title: msg[0].title,
        body: msg[0].body,
        author: msg[0].author,
        postid: msg[0].postid
    }
    const warn = newUser[0].warn
    const newWarn = warn.push(newMsg)
    console.dir(newMsg)
    newUser[0].warned = true
    newUser[0].warn = newWarn
    await newUser[0].save()

Btw, newMsg is set correctly:

And here is where it says 0: 1

This is supposed to be storing newMsg in an array, while keeping the other contents in the array.

Thanks in advance :)

EDIT:

I found the problem, but I am unsure how to fix it.

It has to do with const newWarn = warn.push(newMsg)
