Description

If an exception is thrown in an event handler (such as $.ready), it is silently swalloed.

There are many cases in which exceptions are used to indicate errors for situations that are not code errors, for instance:

var foo = function(arg){
  var result = parseFloat(arg);
  if(isNaN(result)){ 
    throw new Error('not a number');
  }
};

Exceptions like that may be cought by the user, such as when the number is user-input. But they may also indicate errors in the usage of the code (such as foo('123') ), in which case catching them is counter productive since they can't be debugged anymore.
