When setting up users for an app there are two things we need to consider:

1. Who is the user? This is authentication.
2. Given who the user is, what are they able to do/access? This is authorization.

To deal with the first, authentication, we need to set up the following routes. It is very common to put all of these into a router and have that handle an /auth path (profile works too, I'd just already written this).

• GET /register (show the form for sign-up; don't need this route if the form is on another page)
• POST /register (checks user info, creates a user, and starts a session)
• GET /login (shows form for login; again, don't need if this is on a different page)

# What I wrote:

(1..10).inject([]) do |evens, num|
  evens << num if num.even?
end

# Error was 'NoMethodError: undefined method `<<' for nil:NilClass'
# This is saying "You are calling the method `<<` on an object that doesn't have a method by that name, `nil` with class `NilClass`"

# I had been thinking evens was an array which would have a push method and on the first iteration
