# Diamond
The diamond kata takes as its input a letter, and outputs it in a diamond
shape. Given a letter, it prints a diamond starting with 'A', with the
supplied letter at the widest point.
## Requirements
* The first row contains one 'A'.
* The last row contains one 'A'.
* All rows, except the first and last, have exactly two identical letters.
* All rows have as many trailing spaces as leading spaces. (This might be 0).
* The diamond is horizontally symmetric.
* The diamond is vertically symmetric.
* The diamond has a square shape (width equals height).
* The letters form a diamond shape.
* The top half has the letters in ascending order.
* The bottom half has the letters in descending order.
* The four corners (containing the spaces) are triangles.
## Examples
In the following examples, spaces are indicated by `·` characters.
Diamond for letter 'A':
```plain
A
```
Diamond for letter 'C':
```plain
··A··
·B·B·
C···C
·B·B·
··A··
```
Diamond for letter 'E':
```plain
····A····
···B·B···
··C···C··
·D·····D·
E·······E
·D·····D·
··C···C··
···B·B···
····A····
```
## Setup
Go through the setup instructions for JavaScript to
install the necessary dependencies:
http://exercism.io/languages/javascript
## Making the Test Suite Pass
Execute the tests with:
jasmine <exercise-name>.spec.js
Replace `<exercise-name>` with the name of the current exercise. E.g., to
test the Hello World exercise:
jasmine hello-world.spec.js
In many test suites all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
changing `xit` to `it`.
