The thing to remember is that you can mutate an object passed in, but you
can't change it to a new object.
If you need a function that changes a variable, then instead of doing:
function change(obj) {
obj = [];
}
var a = {};
change(a); //won't work
You could do:
function change(obj) {
newObj = [];
return newObj;
}
var a = {};
a = change(a); //this works, because you're assigning the new value
So, if you want to assign something new to a, you have to do it via an
assignment, not via a function call. Hope that makes sense - it's been a
long day...
