Use ES6 syntax. Make sure you are using let/const properly.
Use the built in http api. Do not use any npm modules.
1. Using callbacks print the URLs and their response time. (25 pts)
Requirements
Use Callbacks - Do not block or make a synchronous function for getting times. Just use http.get
getTimes(argument, callback) This function gets the response time from the http request. it calls back to the the calling function.
printTimes(sample) This function should call getTimes(...) and after all response times are gathered - it should then print the times.
HINT: use new Date()
Note - The exact times do not matter - only make sure they are ordered low to high.
const sample = [ 'http://www.google.com/', 'http://www.spotify.com/us/', 'http://twitter.com/', 'http://google.com/nothing' ] // Example Printout // [ // { url: ''http://google.com/nothing', time: 18 }, // { url: 'https://www.google.com/', time: 21 }, // { url: 'https://twitter.com/', time: 31 } // { url: 'https://www.spotify.com/us/', time: 279 } // ]
2. Using Promises print an object that has success and error keys where the value is the URLs that results in success (200 or 300) or errors (400 or 500).
// Example Printout // { // success: ['https://www.google.com/', 'https://www.spotify.com/us/', 'https://twitter.com /' ], // error: [''http://google.com/nothing'] // }
