How to parse static text in Javascript

Question

I have a String that contains a function as a String. This String is returned by the server:

var funcStr = "function() {
    console.log('this is a sample function');
}";

Is it possible to parse this String to a Function and execute it?

Yes its possible `var fn = eval(funcStr);`. Should you do this ever? **NO**. Also, note the unescaped quotes. — Jared Smith, Mar 30 '17 at 13:26
Maybe you should consider fixing the server; that's a weird thing to do. — Pointy, Mar 30 '17 at 13:29

Yes, it is possible, but not a good idea. You use eval. This isn't the best to do for reasons too complex and opinion-based to get into here.
