For each problem, copy the code to a JS Bin. The only tabs needed are Javascript and Console. Try to complete the entire program before hitting "run" to check your work.
// Write a function above these comments called

Stripe's popularity is due largely to its developer-friendliness. Stripe removes much of the messiness from the payment integration process. It verifies credit card information for you, shielding you from the actual data so that your users are secure. It charges the cards for you, and routes the money wherever you want (with some restrictions). But payment gateways are complicated by nature, and even with Stripe, stringing together a payment system for your app can be difficult to conceptualize.
So let's take a look at a basic Stripe integration. There are countless ways to integrate Stripe into your app; we'll cover a simpler method here.
As with many Rails common problems, gems are a great place to start. The Stripe Gem greatly simplifies working with the Stripe API. Add the gem to your Gemfile:

API's either receive data-modifying requests (post, put, delete) or data-accessing requests (get), and in either case, their response can involve retreiving data, serializing that data into JSON, and returning it.
In Rails, this serialization could be done manually, by, say, creating a serializer method:
# User.rb
def serialize
hash = {}
