Check is text valid javascript using javascript without using eval()

Question

Is there any way to do this? Or limit execution time of eval()(e.g. not more then 1 scecond)

@gdoron it seems heavy for my task. Only thing I need is to check is JS valid. I'll use it if there is no anything lite for this. — xander27

Are aware of the risks with eval? those should bother you a lot more than the execution time of it. — gdoron

In my case this JS will be avaliable only for user who write it. So there is no sequrity risks — xander27

Then use JSLint... you know the options, you just need to chose. — gdoron

You could try one of the minifiers, such as UglifyJS. They all include a parser which might be fairly easy to extract (UglifyJS contains a file called "parse-js.js", although I haven't looked at it in detail).
