Question

I’m looking at some example code:

function iLoveCheese(){
    return { 
        'c': thenumber, 'd': anothernumber 
    }
}

Say I want to use ‘thenumber’ in a program, can I just do:-

function lotsOfCheese(){
    var t = iLoveCheese();
    return t.thenumber;
}

Is a correct understanding?

Answer 1

Your lotsOfCheese function is not going to work as excepted. This is because the ILoveCheese function returns an object. You need to reference this object by it’s keys, not it’s values.

function lotsOfCheese(){
  var t = iLoveCheese();
  return t.c; // "c" is the key of the object t
}

This will return a value, thenumber
