| The best way to think about the difference between throwing errors and catching errors is this: you should catch errors only if you know exactly what to do next. The purpose of catching an error is to prevent the browser from responding in its default manner; the purpose of throwing an error is to provide information about why an error occurred. - Zakas, Nicholas C. |
