The introduction to Reactive Programming you've been missing

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.

	/**
	* If argument is a string, try to parse as JSON.
	* Otherwise return null.
	*/
	export function parseOrNull(raw: unknown) {
	if (!raw) return null

	if (typeof raw === 'string') {
	try {
	return JSON.parse(raw)

	# This is a multi-stage build to not spill the contents of the deploy_key
	FROM mhart/alpine-node:10 as base

	# We need git and openssh to resolve `git+ssh` links in package.json
	RUN apk update \
	&& apk add git openssh

	WORKDIR /usr/src
	COPY package*.json ./

	// this code is safe to copy/paste into your browser
	// but you should really try to write it out line-by-line ;)

	// this gist is based on a number of other excellent introductions to lambda calculus
	// classic: https://github.com/sjsyrek/presentations/blob/master/lambda-calculus/lambda.js
	// ornithology: https://www.youtube.com/watch?v=3VQ382QG-y4&t=3349s
	// and this one, in Ruby, called "Programming With Nothing" (excellent title) https://www.youtube.com/watch?v=VUhlNx_-wYk
