everyone! I'm having an issue understanding this program:

var zomB = {

    name: "Zom B.",

    peepsEaten: 5

  },

  zomA = zomB,

  oldHome = "Atlanta",

  newHome = oldHome;

zomA.name = "Zom A.";

//outputs ZomA

console.log(zomB.name);

I'm confused as to why ZomA outputted by the zomB.name. Can someone please explain this?

In JS, objects (alongside 'special' objects like functions and arrays) are passed by reference , whereas primitives (like Strings, Number and Boolean) are passed by value .
