JavaScript deals with them by throwing exceptions as well but unlike Java, it does have any concept of checked Exceptions. The JS interpreter just stops. And this has some interesting implications in hybrid scenarios like a Webview based app. Consider a simple Android app where most of the code is in JavaScript but is making a request to Java layer....
