  • I generally stub out the console (based on firebug) for browsers without one. I also tend to throw an error within try/catch blocks. I really don't see an inherit advantage here.

    try {
    var tmp = doSomething();
    if (tmp == something.errorCondition)
    throw new Error("Error condition in X");
    } catch(err) {
    //handle ((err && err.message) || err.toString())
    }
  • Throwing an exception within a try block will just catch the exception in the catch-block - whats the point?

    I can use jquery.error like this
    <script type="text/javascript">
    jQuery(function(){jQuery.error = console.error;
    console.log("My test message");
    jQuery.error("mytest error message");

    });
    </script>

    Is there any other ways or advantages of this jQuery.error usage?
