    What you are seeing is something called pass by value, as opposed to pass by reference. It means that JavaScript copies the values of the variables into the function arguments.

        sameString = 'New String';

    function increaseAge(obj) {
        obj.age += 1;
    function Test()

          name: 'SmartBear',
          age: 25,
