The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

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.

React (Virtual) DOM Terminology

In React's terminology, there are five core types that are important to distinguish:

ReactElement / ReactElement Factory
ReactNode
ReactComponent / ReactComponent Class

React Elements

In all the discussions about ES6 one thing is bugging me. I'm picking one random comment here from this io.js issue but it's something that comes up over and over again:

There's sentiment from one group that Node should have full support for Promises. While at the same time another group wants generator syntax support (e.g. var f = yield fs.stat(...)).

People keep putting generators, callbacks, co, thunks, control flow libraries, and promises into one bucket. If you read that list and you think "well, they are all kind of doing the same thing", then this is to you.

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

	var EventEmitter = require('events').EventEmitter,
	_ = require('lodash');

	/**
	* Creates an action functor object
	*/
	exports.createAction = function() {

	var action = new EventEmitter(),
	eventLabel = "action",

	#!/bin/bash
	# This script will install a Git pre-push hook that prevents force pushing the master/main branch.
	# There are three variants that I have built:
	# - pre-push: prevents force-pushing to master/main.
	# - pre-push-2: prevents force-pushing to master/main depending on the remote (you need to edit the file!).
	# - pre-push-3: prevents any type of pushing to master/main.
	# Set the desired version like this before proceeding:
	# FILE=pre-push

	# Single repo installation:

	<html>
	<head>
	<style>
	b {
	font-weight: normal;
	}
	</style>
	<script src="http://cdn.jsdelivr.net/handlebarsjs/2.0.0/handlebars.js"></script>
	</head>
	<body>

	(function(window){

	var EVENT_EXISTS = 'GlobalEvents: Event already exists.';

	var eventIsRunning,
	_eventStack,
	_findByName,
	stackEvent,
	removeEvent,
	eventListener,

	const createNode = html =>
	new Range().createContextualFragment(html).firstElementChild;
