Updating and/or setting values of object properties stored in variables

This is my freeCodeCamp full example.

Basically I can do this 

collection[id][prop] = value;

but not 

var idProperty = collection[id][prop];
idProperty = value;

I have marked this point in the freeCodeCamp code with a comment.

This is obvious why I can't do this, but I don't know how else to do it. Thanks alot :-)

It looks like you're trying to create a reference or alias. This is a feature of some languages (C++ for example), but it's not available in JavaScript.
