You're Missing the Point of Promises

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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

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.

Problem

For fun, let's say you are programming in a language that doesn't allow variable assignments and you still want to make a recursive function. Although you can't assign variables, you can use functions (and enclosed function arguments). Can you make a function recursive without calling it by name?

Lets try implementing the factorial function. First with a function calling itself by name, then with a funtion that never calls itself by name

Here is the implementation of factorial that calls itself by name. It's a simple recursive function
