tk120404 / promises.md
Created August 22, 2014 09:24 — forked from domenic/promises.md

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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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

What is the student_id of the lowest exam score above 65? Mongodb
db.grades.aggregate({ $match : { score : { $gte : 65 }, type:'exam' }}, { $group:{_id:'$student_id',count:{$sum: 1}, score :{ $min:'$score'}}}, {'$sort':{'score':1}}, {'$limit':1});
