Passing a pointer/reference to a variable as parameter

Question

I know this question has been asked multiple times (yes, I did some research) but I can\'t see to find a solution that fits my needs.

What I have done so far:

Answer 1

In JavaScript values such as integers, strings, etc. are passed by value. If you want to pass a reference, you have to pass an object into the JavaScript function. (JavaScript objects are passed by reference)

function adjustValues(referenceObject) {
    referenceObject.foo = 2;
    referenceObject.bar = "newValue";
}

referenceObject = {
  foo: 1,
  bar: "initialValue"
};

adjustValues(referenceObject);
