ZEON.js

Zeon.js is a tool that helps you find problems in your JavaScript / ECMAScript.

A proof of concept analyze tool by Peter van der Zee, © pvdz.ee, April 2011.

See a full description here. And the full page repl.

It uses a custom parser and statical analysis to bring your attention to possible problems.

Use this zeonify bookmarklet to enable Zeon.js for any textarea on any page! Example:

setTimeout(function () { var m = new Image(); m.src="images/modal.gif"; var trail = $("#trail"), function westward() { var l = trail.width(); wagon.css({ left: l }).animate({ left: -150 }, 20000, westward); } westward("Ho!"); wagon.click(dysentery); $("#overlay").live("click", function(e) { $("audio")[0].pause(); $("#overlay").remove(); $("#smallbox").remove(); }); }, 10);

The poc was built and developed using Chrome(11). It will also (at least kind of) work in Firefox 4, IE 9 and Safari 5. It won't work on Opera and probably not on mobile. Chrome is recommended for larger scripts because it seems to be faster at the time of writing.

Please note that at least for the time being this software is closed and may not be used in third party software without my explicit consent. If you'd like to use my js parser or this tool in another project you can always just contact me through twitter at @kuvos.
