let fs = require('fs');
 
let handleRequest = (request, response) => {
    response.writeHead(200, {
        'Content-Type': 'text/html'
    });
    fs.readFile('./index.html', null, function (error, data) {
        if (error) {
            response.writeHead(404);
            respone.write('Whoops! File not found!');
        } else {

        }
        response.end();

    }       
    http.createServer(function(request, response) {  
        response.writeHeader(200, {"Content-Type": "text/html"});  
        response.write(html);  
        response.end();  
    }).listen(8000);
