前提: 完成していて、比較的支持を集めていて、JavaScriptを中心にした書籍 (DOM APIよりは言語を中心とした内容)

最初からES2015で学ぶことを前提にした初心者〜中級者向けのJavaScript本がなかったので書いてる。 ES2015でJavaScriptという言語のコア部分は大きく変わったので、それを前提とした内容にする予定。

Why I hate TypeScript

Warning: These views are highly oppinated and might have some slightly incorrect facts. My experience with typescript was about 2 weeks in Node and a week in angular2.

Not Standard

TypeScript is implementing their own take on JavaScript. Some of the things they are writing will likely never make it in an official ES* spec either.

Technologies that have competing spec / community driven development have a history of failing; take: Flash, SilverLight, CoffeeScript, the list goes on. If you have a large code base, picking TypeScript is something your going to be living with for a long time. I can take a bet in 3 years JavaScript will still be around without a doubt.

Its also worth noting that they have built some things like module system and as soon as the spec came out they ditched it and started using that. Have fun updating!

	require "active_record"

	namespace :db do

	db_config = YAML::load(File.open('config/database.yml'))
	db_config_admin = db_config.merge({'database' => 'postgres', 'schema_search_path' => 'public'})

	desc "Create the database"
	task :create do
	ActiveRecord::Base.establish_connection(db_config_admin)

	# encoding: utf-8

	require "timeout"

	# Capture the standard output and the standard error of a command.
	# Almost same as Open3.capture3 method except for timeout handling and return value.
	# See Open3.capture3.
	#
	# result = capture3_with_timeout([env,] cmd... [, opts])

	module RailsAppName
	class Application < Rails::Application
	# .... your settings

	require "#{Rails.root}/lib/cloud_flare_middleware"
	config.middleware.insert_before(0, Rack::CloudFlareMiddleware)

	# ... your settings
	end
	end
