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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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.
| package object mail { | |
| implicit def stringToSeq(single: String): Seq[String] = Seq(single) | |
| implicit def liftToOption[T](t: T): Option[T] = Some(t) | |
| sealed abstract class MailType | |
| case object Plain extends MailType | |
| case object Rich extends MailType | |
| case object MultiPart extends MailType |
The diff output is more specific:
[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.
>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.
