#Lessons From A JavaScript Code Review

I was recently asked to review some code for a new JavaScript application and thought I might share some of the feedback I provided as it includes a mention of JavaScript fundamentals that are always useful to bear in mind. Code reviews are possibly the single biggest thing you can do to improve the overall quality of your solutions and if you're not actively taking advantage of them, you're possibly missing out on bugs you haven't noticed being found or suggestions for improvements that could make your code better.

##Challenges & Solutions

Code reviews go hand-in-hand with maintaining strong coding standards. That said, standards don't usually prevent logical errors or misunderstandings about the quirks of a programming language. Even the most experienced developers can make these kinds of mistakes and code reviews can greatly assist with catching them.

Often the most challenging part of code reviews is actually finding an experienced developer you trust to complete

Continuous CoffeeScript testing with Guard and Jasmine

This Gist shows how to set up a Rails project to practice BDD with CoffeeScript, Guard and Jasmine. You can see this setup in action on Vimeo

Install Gems with Bundler with bundle install
Define your guards with mate Guardfile
Initialize Jasmine with bundle exec jasmine init
Configure Jasmine with mate spec/support/yasmine.ym
Start Guard with bundle exec guard

	class ApplicationController < ActionController::Base
	TOKEN_PLACEHOLDER = "__CROSS_SITE_REQUEST_FORGERY_PROTECTION_TOKEN__"

	after_filter :inject_csrf_token

	private

	def inject_csrf_token
	if protect_against_forgery? && token = session['_csrf_token']
	if body_with_token = response.body.gsub!(TOKEN_PLACEHOLDER, token)

	# autoload concerns
	module YourApp
	class Application < Rails::Application
	config.autoload_paths += %W(
	#{config.root}/app/controllers/concerns
	#{config.root}/app/models/concerns
	)
	end
	end

	You are trying to install in deployment mode after changing
	your Gemfile. Run `bundle install` elsewhere and add the
	updated Gemfile.lock to version control.

	You have deleted from the Gemfile:

	* rb-fsevent
