This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.

| function scrollToAnchor(aid){ | |
| var aTag = $("a[name='"+ aid +"']"); | |
| $('html,body').animate({scrollTop: aTag.offset().top},'slow'); | |
| } | |
| scrollToAnchor('id3'); | |
| function scrollTo($element){ | |
| $('html,body').animate({scrollTop: $element.offset().top},'slow'); | |
| } |

| -Write the code according to the navigator's specification | |
| -Listen intently to the navigators instructions | |
| -Ask questions wherever there is a lack of clarity | |
| -Offer alternative solutions if you disagree with the navigator | |
| -Where there is disagreement, defer to the navigator. If their idea fails, get to failure quickly and move on | |
| -Make sure code is clean | |
| -Own the computer / keyboard | |
| -Ignore larger issues and focus on the task at hand | |
| -Trust the navigator - ultimately the navigator has the final say in what is written |

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
