Re:How evil is eval?

@seven - I think the reason for the article was to demonstrate that eval is sometimes necessary - the proof is that even Douglas Crockford himself uses it in his parse JSON method, as do JQuery and Prototype frameworks - and he shows us the examples. I was pretty impressed

Good point, but I still believe that most uses of eval are completely unnecessary and are a result of not knowing the 'power' of the used language.
To quote Crockford: “eval is Evil: The eval function is the most misused feature of JavaScript. Avoid it”
To avoid something does not mean to never use it at all.
The reason I commented this article was perhaps a bit.. hmm.. lets say I was in a bad mood. I felt the author just took a prominent name, a quote, and then he stated the obvious.
Crockford is talking about misusing. I probably do not know enough about javascript to know for sure, but I would guess that his use of eval is not a 'misuse'.
