So, I'm going to go ahead and create a variable for events,…and I will require the events module.…Now, the EventEmitter itself is a constructor.…So, I'm going to create a new instance of a variable…called emitter.…So, we'll create a new instance of the emitter…by using the new keyword…with the event module, .Event Emitter.…There is the function that we want to use.…So, the EventEmitter is constructor,…and we're going to create a new instance…of the EventEmitter.…Now, this object that we created here on line 3…
Alex Banks shows how to install Node.js on a Mac or PC and work with the Node.js core: the global object, event loop, http module, and file system. Then he covers reading and writing data, streaming data, making http requests, and working with the node package manager (npm). In the final chapters, he shows how to start sessions on web servers, communicate with web servers and clients with WebSockets, use the Express framework to develop applications, and test and debug Node.js code. Want to speed up your Node.js workflow? Check out the tutorials on automating tasks with Grunt and npm scripts.
