app.js

//WE SHOULD ALWAYS USE SOME REFERENSE CODE THROUGH WHICH WE CAN COPY SOME THINGS FROM THAT CODE TO OUR CODE
//WHEN WE MAKE A NEW PROJECT LIKE THIS  THEN WE HAVE TO DO:
// 1. MAKE A APP.JS
// 2. IMPORT ALL THE MODULES
// 3. WRITE npm init
// 4. INSTALL EXPRESS AND PUG
// 5. INSTALL MONGNOOSE
// 6. INSTALL BODYPARSER
// 5. MAKE TWO FOLDERS VIEWS AND STATIC
// 6. INSIDE STATIC MALE IMG FOLDER, INDEX.JS ,  JAVASCRIPT FILE ,CSS FILE
// 7. INSIDE VIEWS MAKE ALL PUG FILE
