Node.js is an event-based, non-blocking, asynchronous I/O framework that uses Google's V8 JavaScript engine. It is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code...

In C, some expressions yield undefined behavior. The standard explicitly chooses to not define how a compiler should behave if it encounters such an expression. As a result, a compiler is free to do whatever it sees fit and may produce useful results, unexpected results, or even crash. Code that i...
