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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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.
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

#The Functional Programmers Cheat Sheet for NDC Oslo 2014
This year NDC Oslo has a full three-day functional programming track with an amazing lineup. If you agree that the future of programming is FP, use this as your "auto pilot" guide on what sessions to attend.
Cheer for sessions on Twitter using the #ndcoslo and #fptrack hashtags.
[The full agenda (including non-fp sessions) is here].

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

So the general concept behind an artificial intelligence is quite simple. It's basically just a replication of what we see in other sentient beings. It has been abstracted to mean things like speech, the ability to play a game well, to guess a person's motives and intentions, and to use that against them in order to win. The reason this seems like a form of intelligence to us, a being with sentience, is because as humans, we see anything with an understanding of anything to be sentient. Almost, anyway. An understanding is a very important part, but where it really hits
You can now read this on my (pretty) website! Check it out here.
Every reason to get more HackerPoints™ is a good one, so today we're going to
write a neat command line app in .NET Core! The Common library has a really cool
package Microsoft.Extensions.CommandlineUtils to help us parse command line
arguments and structure our app, but sadly it's undocumented.
No more! In this guide, we'll explore the package and write a really neat
This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.
While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
Arrow functions create a concise expression that encapsulates a small piece of functionality. Additionally, arrows retain the scope of the caller inside the function eliminating the need of self = this.
// const multiply = function(x,y) {
