if I am not mistaken eval executes valid code in a given string

eval("alert('hey')");

and

setTimeout("alert('hey')",1000);

does just about the same thing, only with a timer. is set timeout just as risky as eval?

A: 

Because when people say "eval", they mean "eval and any function that is more or less equivalent to eval", but the former is much shorter to say. So the answer to your question is yes, it is as risky.

I'd say you hear the same objections. setTimeout (with string and not function parameters) is pretty much the same as eval.

If possible,

 setTimeout(function(){ alert ("hey") ; }, 1000);

No reason it shouldn't be possible

+1 for providing an example of the proper use of `setTimeout`. The ability to pass a string argument has probably done more harm than good to how people use javascript

+1 Looks like my code needs some security changes ;) thanks, hmm I was not exactly aware that you can use timeouts this way as well hmmm
