Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

	#!/usr/bin/env bash

	# Abort sign off on any error
	set -e

	# Start the benchmark timer
	SECONDS=0

	# Repository introspection
	OWNER=$(gh repo view --json owner --jq .owner.login)


	/*
	##Device = Desktops
	##Screen = 1281px to higher resolution desktops
	*/

	@media (min-width: 1281px) {

	//CSS

	# Print a label on a Zebra TLP 2844 in Ruby.
	# The printer is EPL/2 capable and connected via USB.
	# EPL/2 reference: http://www.zebra.com/apps/dlmanager?dlp=-227178c9720c025483893483886ea54a70963bb77ca94fcc1d65ce9394326ed960e43d023beba35831d5d9bfc1740296347157b5024977a&c=gb&l=en

	# https://github.com/larskanis/libusb
	require 'libusb'

	# Select the printer by vendor ID and product ID.
	# To get a list of connected devices, use 'lsusb'.
	# 0a5f:0x000a identifies the Zebra TLP 2844.

	def is_valid_singapore_nric_number(number):
	number = number.upper()
	prefix = 0 if number[0] in "SF" else 4
	table = "JZIHGFEDCBA" if number[0] in "ST" else "XWUTRQPNMLK"
	check = (prefix + sum([int(number[i + 1]) * int(a)
	for i, a in enumerate("2765432")])) % 11
	return table[check] == number[-1]
