Slip 4 - A) Create a Node.js Application that accepts first name, last name and date of birth of a Person and define a Module that concatenate firstName and lastName andalso calculate the age of the Person.

Solution:

 var http = require('http');

var rl = require('readline').createInterface({

    input: process.stdin,

    output: process.stdout

});

rl.question('Enter The First Name : ', (name) => {

    rl.question('Enter The last Name :  ', (lname) => {

        rl.question('Enter The Date of Birth :  ', (inputdate) => {

        var fn = name;

        var ln = lname;

        var dob = new Date(inputdate);

        var today = new Date();

        var diff = new Date(today.getTime() - dob.getTime());

        console.log(`first Name is : ${fn}`);

        console.log(`Last Name is : ${ln}`);

        console.log("Age: " + Number(diff.getUTCFullYear() - 1970));

        rl.close();

        http.createServer(function (req, res) {

            res.writeHead(200, { 'Content-Type': 'text/html' });

            res.write("First Name is : " + fn);

            res.write("Last Name is : " + ln);

            res.end();

        }).listen(3000);

    });

});

});
