JavaScript

var myObject = {};

var copyOfMyObject = myObject; // not copied by value, just the reference is copied

myObject.foo = 'bar'; // manipulate the value stored in myObject

/* Now if we log myObject & copyOfMyObject, they will have a foo property because they reference the same object. */

console.log(myObject, copyOfMyObject); // logs Object '{ foo="bar"} Object { foo="bar"}'
