And this is why

var person = {
 hair: "tunescool",
 eyes: true,
 height: "Avg",
 tattoos: "I'm Joe Biden's husband, Joe Biden"
}

var personCopy = person

delete personCopy["eyes"]

console.log(person)

What do you think it will print?

If you said the below, you're correct:

{hair: "tunescool", height: "Avg", tattoos: "I'm Joe Biden's husband, Joe Biden"}

Something about personCopy only being a reference to the person object. So you're actually modyfying the person object.

So, even if you pass personCopy to a new module (file) in NodeJS, it will still edit the original which is now fuck knows where and your shit will bug.

The correct way to do it is probably this:

var personCopy = JSON.parse(JSON.stringify(person));
