// http
// Agr ham bina res(response) ko end kare banayege toh usko koi end point nahi milega aur voh chalta rahega isliye we write res.end();
// Aur hamne jo server create kara hai usko listen bhi karna hoga (port define karna hoga) toh usko .listen(port) likhte hai 
// res.write() wale function se ham write kar skte hai 
// res.writeHead se ham content jo de rhe hai voh bata sakte hai ki kya hai text hai ya html ya pug.
// res.writeHead me pehli cheej hoti hai status code jo jada tar ham 200 hi lenge then uske baad content type 
// listen me aur function bhi daal sakte hai jaise console.log()

// Iske baad nodemon istallation tha and nothing new to learn 
// Bas jab bhi nodemon laga ke run kare file toh end me .js jarur lagayio varna voh index.js ko run karega
