When you start working with WebPack for GameTime, you'll notice that you can't just define a variable in one file and find it in another as easily as you can in Rails.

Fork this gist and answer the following questions:

• In the context of Node, what is a module?

**Step One**: Watch [Sorting Algorithms in JavaScript](https://www.youtube.com/watch?v=uRyqlhjXYQI)

**Step Two**: Fork this gist.

**Step Three**: Respond to this question in your fork: "What are some of the balances and trade offs between different sorting algoritms?"

Fast algorithms can take up a lot of memory, and vice versa. ie. merge sort takes up a ton of space but is much faster than insertion sort that is slower but also takes up less memory.  This is a particularly important consideration if you are working with very large sets of data.  Bubble sort can be twice as slow as insertion sort even if it has a smaller amount of data.

**Step Four**: _Totally Optional_: take a look at some of the other forks and comment if the spirit moves you.

1. Define CRUD. CRUD is an acronym that stands for create, read, update and delete. These four words correspond to the verbs in HTTP. In order to have full CRUD functionality within a Sinatral app, the app must be able to do all four of these things.
2. There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for. i. Read '/tasks' & GET shows view of all tasks from index.erb ii. Read '/tasks/:id' & GET shows view of a specific task from show.erb iii. Create 'tasks/new' & GET makes form to create a new task in new.erb iv. Create '/tasks' & POST sends data to the server and redirect to '/tasks' v. Update '/tasks' & GET makes a form to input and update an existing task from edit.erb vi. Update '/tasks/:id/edit' & PUT sends data to the server to update existing task information vii. Delete '/tasks/:id' & Delete deletes existing information
