Accueil | The Hacking Project nodejs-introduction Asynchronous programming Node.js is entirely asynchronous consider this analogy... You go down to a fast food joint and order a cheeseburger, they will immediately take your order and then make you wait around until the cheeseburger is ready. In the meantime they can take other orders and start cooking cheeseburgers for other people. Imagine if you had to wait at the register for your cheeseburger, blocking all other people in line from ordering while they cooked your burger! Node.js is entirely asynchronous You have to think differently What's the output? echo 'Hello'; sleep(2); echo ' world Node.js setTimeout(function () { console.log(' world.') }, 2000) console.log(' Hello'); Node.js is entirely asynchronous You have to think differently Failure to understand the event loop and I/O based model could lead to anti-patterns (bad code) Node uses an event-loop to perform non-blocking and asynchronous I/O consider this jQuery code... $.post('/resource.json', function (data) { console.log(data) });
