web scriping in javascript

 npm init -y     type this in terminal

npm install request


npm js request


it should contain a function with a request URL and one callback function 

with the help of cheerio we can manipulate the data 

const request = require('request');
request('http://www.google.com', function (error, response, body) {
  console.error('error:', error); // Print the error if one occurred
  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
  console.log('body:', body); // Print the HTML for the Google homepage.
});
