Say, you got a JSON like this, and you want to add to the albums array

    "username": "Kanye West",
    "type": "Human",
    "profession": "Artist",
    "albums": [],
    "_id": "154f6259-4d8b-4a60-888c-dade18524003"

You would do something like this

db.find({username: "Kanye West"})
    .then((data) => {
        data.result[0].albums.push("The College Dropout")
        data.result[0].albums.push("Late Registration")
        data.result[0].albums.push("The Blueprint")
        data.updateOne(0).then((data) => {

Problem solved!

This is where having a Data class really helps, you can interact and update the data with the methods you already know.

Wait, what? I just remembered, "The Blueprint" isn't a Kanye West problem, I think I can fix this..

db.find({username: "Kanye West"})
    .then((data) => {
        data.updateOne(0).then((data) => console.log(data))

Okay, fixed!
