[Async]: Promises, Promises

An introduction to asynchronous flow control in JavaScript, focussing on jQuery.Deferred

9 February 2012 from 7:15pm to 9:30pm

Currently in read only mode, sorry about that, please try again in a few hours.

This session, with Premasagar Rose, is an introduction to asynchronous flow control in JavaScript. We’ll be looking at how to cleanly handle multiple callbacks from Ajax requests, setTimeouts, loading images and other asynchronous routines. In particular, we’ll focus on jQuery.Deferred, which implements the Promises design pattern.

We’ll work through some practical, step-by-step code examples, looking at how jQuery uses promises with all of its Ajax methods, see how they can control and interact with jQuery’s animation effects, and how jQuery.Deferred can be used to create custom promises that control the flow of a website or web application.

Prem is the principal of local web applications company, Dharmafly, is a hacker and mentor at Rewired State, and helps to run Async.
