CatchJS automatically collects all uncaught exceptions from your users' browsers, and presents a detailed log of their circumstances. This includes the browser type, the stack trace, and even screenshots and the click trail which lead to the error.
catchjs.log("Unexpected parameter: ", obj);
It's not just for errors. The catchjs.log() API gives you a persistent remote log. This lets you log objects and text from your users' device, so you can inspect the data later.
