eval()

[davej]

So when does eval() have a legitimate and perfectly safe usefulness?

I don't think a good program would ever need to use it. Except maybe browser that don't support JSON.parse(), but I did build my own JSON.parse() function once just for the experience in order to avoid the use of eval().

 

Actionscript used to have eval() and they removed it in ActionScript 3, so they know eval is useless.

For some things we have our server sending blocks of Javascript code to the browser, that's really the only time I would use it. Eval is better in that situation than creating a new script element with the code and adding it to the page.
