javascript - Alter and Assign Object Without Side Effects

I currently have the following code:

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

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

myElement.id = 2;
myElement.value = 3;
myArray[1] = myElement;

The problem is that when I change the value of id and value for my second element, the values also change in the first element. Is there a way that I can keep adding new elements without it changing the value of the previously inserted values in the array?

See Question&Answers more detail:os

Try this instead:

var myArray = [];

myArray.push({ id: 0, value: 1 });
myArray.push({ id: 2, value: 3 });

or will this not work for your situation?
