Alter and Assign Object Without Side Effects

Question

I currently have the following code:

var myArray = [];
var myElement = {
  id: 0,
  value: 0
}

myElement.id = 0;
myElement.value = 1;
myArray[0] = myElement         


        

Answer 1

This is a textbook case for a constructor function:

var myArray = [];

function myElement(id, value){
    this.id = id
    this.value = value
}

myArray[0] = new myElement(0,1)
myArray[1] = new myElement(2,3)
// or myArray.push(new myElement(1, 1))
