Updating Properties

Say, you got a JSON like this, and you want to change the type of them

{
    "username": "Vito Corleone",
    "type": "Human",
    "_id": "5fc4e2e1-b84a-4934-87d0-f8ca595e63f2"
},
{
    "username": "Tom Hagen",
    "type": "Human",
    "profession": "Lawyer",
    "_id": "d0db9648-215e-44a6-a974-669a02337338"
},
{
    "username": "Micheal Corleone",
    "type": "Human",
    "_id": "577c1352-7e8d-4716-89e0-7b1e28e8c3ec"
},
{
    "username": "Kay",
    "type": "Human",
    "_id": "8ae63a7d-7665-4d90-8391-cd91ef3d8702"
}

You can do it like this

db.find({type: "Human"}).then((d) => {
    d.result.forEach((e) => e.type = "Fictional Characters")
    d.updateAll().then((d) => console.log(d))
})

Properties updated!

Adding Properties

That's really easy too.

You can do it like this

db.find({type: "Human"}).then((d) => {
    d.result.forEach((e) => e.legs = 2)
    d.updateAll().then((d) => console.log(d))
})

This will update all the type: "Humans" objects with a property of legs and its value will be 2. Handy, right?

Deleting Properties

Want to delete properties? Set them to undefined!

db.find({ username: "Kanye West" })
    .then((data) => {
        data.result[0].type = undefined 
        data.updateAll()
    })

"There you go! Now you know everything" Someone once said to me. But of course I didn't knew everything. but yeah uh lets move on...
