I have written some Javascript (specifically a jQuery plugin) in which I replace the contents of some tags with the result of an eval to give me some kind of templating mechanism.
My question is: Will using eval() over and over cause a problem with memory?
The reason I ask is that when I look at the loaded scripts with Firebug, I see all the eval’ed code listed there, so my worry is that if the user uses this application in the browser, it might cause a problem with memory.
Apart from it being a bad idea to use eval, there will almost certainly be some memory overhead in setting it up.
Also eval code won’t be as optimised** as there is no chance for caching or other optimisations.
** depending on browser.
