JSLint “eval is evil.” alternatives

Question

I am have some JavaScript functions that run on both the client (browser) and the server (within a Java Rhino context). These are small functions - basically little validators

Answer 1

I would avoid using eval in all situations. There's no reason you can't code around it. Instead of sending code to the client, just keep it hosted on the server in one contained script file.

If that's not doable, you can also have a dynamically generated javascript file then pass in the necessary parameters via the response, and then dynamically load the script on the client side. There's really no reason to use eval.

Hope that helps.
