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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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.
any
: magic, ill-behaved type that acts like a combination of never
(the proper [bottom type]) and unknown
(the proper [top type])
never
is assignable to any
, and any
is assignable to anything at all.any & AnyTypeExpression = any
, any | AnyTypeExpression = any
unknown
: proper, well-behaved [top type]
unknown
. unknown
is only assignable to itself (unknown
) and any
.unknown & AnyTypeExpression = AnyTypeExpression
, unknown | AnyTypeExpression = unknown
any
whenever possible. Anywhere in well-typed code you're tempted to use any
, you probably want unknown

This is some sort of answer to recent posts regarding Web Components, where more than a few misconceptions were delivered as fact.
Let's start by defining what we are talking about.
As you can read in the dedicated GitHub page, Web Components is a group of features, where each feature works already by itself, and it doesn't need other features of the group to be already usable, or useful.
