I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

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

For reference, this is the way I managed to do it as of March 2016 starting with the link mentioned in this comment:

Added HEROKU_API_LOGIN (from heroku auth:whoami) and HEROKU_API_KEY (from heroku auth:token) as protected ENV variables in the travis.org build settings. Alternatively, they can be added in the .travis.yml with:
```
travis encrypt HEROKU_API_LOGIN ="$(heroku auth:whoami)" --add
travis encrypt HEROKU_API_KEY="$(heroku auth:token)" --add
```
Added following lines to the .travis.yml:

	=Navigating=
	visit('/projects')
	visit(post_comments_path(post))

	=Clicking links and buttons=
	click_link('id-of-link')
	click_link('Link Text')
	click_button('Save')
	click('Link Text') # Click either a link or a button
	click('Button Value')

	#301 Redirects for .htaccess

	#Redirect a single page:
	Redirect 301 /pagename.php http://www.domain.com/pagename.html

	#Redirect an entire site:
	Redirect 301 / http://www.domain.com/

	#Redirect an entire site to a sub folder
	Redirect 301 / http://www.domain.com/subfolder/

	function countCSSRules() {
	var results = '',
	log = '';
	if (!document.styleSheets) {
	return;
	}
	for (var i = 0; i < document.styleSheets.length; i++) {
	countSheet(document.styleSheets[i]);
	}
	function countSheet(sheet) {
