Slip 7 Create a node js file named main.js for event-driven application. There should be a main loop that listens for events, and then triggers a callback function when one of those events is detected.

 // import event module var events = require('events'); // create an eventEmitter object var eventEmitter = new events.EventEmitter(); // create an event handler var connectHandler = function (s) {    console.log('Its', s); }; // Bind the data_received event eventEmitter.on('data_received', function (name) {    console.log(name, "Understood event -Driven"); }); // trigger data_received event eventEmitter.emit('data_received', "FYMSC(CS)"); // Bind the connection event eventEmitter.on('connection', connectHandler); // trigger connection event eventEmitter.emit('connection', "SIMPLE SOLUTION"); console.log("program Ended");
