JSON

Given I have the following: (which is dynamically generated and varies in length)

associations = ["employer", "address"];

Trying to traverse the JSON object, and wanting to form something like the following:

data.employer.address

or

data[associations[0]][association[1]]

Without doing this:

eval("data."+associations.join('.'));

Finally, I may be shunned for saying this, but is it okay to use eval in an instance like this? Just retrieving data.

Here's the deal, we have a big JS library that we want to compress, but YUI compressor doesn't fully compress the code if it finds an "eval" statement, out of fear that it will break something else.

In JavaScript is there a way to get the "value" of a statement in the same way that function() { return eval("if (true) { 1 }"); } returns "1"; function() { return if (true) { 1 } } and all similar permutations I've tried are not valid syntax.
