Javascript 'eval' problem?

I’m trying to do something simple in Javascript, which is to receive JSON data and insert that data into some variables. The line that’s giving me a problem reads like this:

myData = eval(’(’ + value.responseText + ’)’);

That, by the way, is exactly the way that ever example I’ve ever seen, be it in books or on the web, is written. Exactly. Even cut & pasted and just changing the variable name. Whenever I use it I always get a really vague error that says:
syntax error
()

Firefox is only slightly helpful in pointing to the end of the line and I’m assuming that this ass-stupid thing is saying that I’m missing a semicolon. Which, clearly, I am not.

The data I’m getting back to the server is correct. That data is:
{“date”:“2011–01-19”,“title”:“Fixes”,“author”:“Me”,“content”:“Bogus test”,“newsid”:“4”}

I found that I was required to create an array using:
var myData = new Array()

And, indeed, if I do this all manually like this:
var myData = new Array({“date”:“2011–01-15”,“title”:“Fixes”,“author”:“Me”,“content”:“Bogus test”,“newsid”:“4”});

Then my code works perfectly. But this:
var myData = new Array(eval(’(’ + value.responseText + ’)’));
gives me the same () error. If I do this:
var myData = new Array(eval(value.responseText));
then I get an error saying myData[0] is undefined.

If somebody could please tell me what’s wrong I would appreciate it. If someone could point me to a resource, somewhere in the world, that is correct I’d appreciate it.
