1. Define CRUD. create, read, update, delete

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. read: get, read: get, create: get, create: post, update: get, update: put, delete:, delete

3. Why do we use set method_override: true? to set the form to put or delete instead of the default value of post. We override the verb.

4. Explain the difference between value and name in this line: ``.

## Models, Databases, Relationships in Rails

#### What is the difference between a primary key and a foreign key? Where would we find a primary key? What would it be called by default? Where would we find a foreign key? What is the naming convention for a foreign key?
  We find a primary key as the main identifier of a table. Example: Teachers: TeacherId. A Foreign creates the relationship between tables.
  Example: Teachers : course_id. The naming convention for these are the table they  belong to + "_id" 

#### Write down one example of:
* a `one-to-one `relationship.
  each person has one toothbrush and one toothbrush has one person. This is modeled by combining both to a single table because they are 
  dependent of eachother

What does it mean to concatenate files? Find an image of an example concatenated file. Why would we want to concatenate files?
 Combine files. This will increaase performance and provide an efficient package that our browser can interpret

What does it mean to precompile files? What does this have to do with coffeescript and sass files?
  Sass -> CSS, CS -> JS. Our browser needs CSS/JS/HTML. Sass and CS abstractions of their base language/
  
What does it mean to minify files? Find an image of an example minified file. Why would we want to minify files?
  Strip whitespace and uneeded data. This will increaase performance and provide an efficient package that our browser can interpret

Start up the server for Catch 'em All (rails s) and navigate to http://localhost:3000/assets/application.js. Then open up the code for application.js in your text editor. Why are these not the same?

### Leap

##Leap
My code: [here](https://github.com/Jbern16/exercism/blob/master/javascript/leap/leap.js)
* Responder #1 ([here](http://exercism.io/submissions/9b50b27c92fb45a2848639bbce4d95ae) - This user used a super a clean conditional statement and logic to solve this problem. He broke out what a leap is instead of nesting a conditional and and responding with a boolean directly. I think this approach was very good.

* Responder #2 ([here](http://exercism.io/submissions/5f87d2e1f50242c08904e065dea8dad5) - This user used a similar broken down condiional as I did, however with more conditions. Although morereadable it creates a longer conditional which I am not a fan of doing.

* Responder #3 ([here](http://exercism.io/submissions/aa2c5470f91441ac9c5af928ec58092d) - This user used one very long, one line conditonal. Although short, It is not readable and a little too clever. By breaking it down multiple lines its easier to reason about.
