# Raindrops
|
||
|
|
|
||
|
|
Convert a number to a string, the contents of which depend on the number's factors.
|
||
|
|
|
||
|
|
- If the number has 3 as a factor, output 'Pling'.
|
||
|
|
- If the number has 5 as a factor, output 'Plang'.
|
||
|
|
- If the number has 7 as a factor, output 'Plong'.
|
||
|
|
- If the number does not have 3, 5, or 7 as a factor,
|
||
|
|
just pass the number's digits straight through.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
- 28's factors are 1, 2, 4, **7**, 14, 28.
|
||
|
|
- In raindrop-speak, this would be a simple "Plong".
|
||
|
|
- 30's factors are 1, 2, **3**, **5**, 6, 10, 15, 30.
|
||
|
|
- In raindrop-speak, this would be a "PlingPlang".
|
||
|
|
- 34 has four factors: 1, 2, 17, and 34.
|
||
|
|
- In raindrop-speak, this would be "34".

## Elm Installation
|
||
|
|
|
||
|
|
Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
|
||
|
|
installation and learning resources.
|
||
|
|
|
||
|
|
## Writing the Code
|
||
|
|
|
||
|
|
The first time you start an exercise, you'll need to ensure you have the
|
||
|
|
appropriate dependencies installed.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm install
|
||
|
|
```
|
||
|
|
|
||
|
|
Execute the tests with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm test
|
||
|
|
```
|
||
|
|
|
||
|
|
Automatically run tests again when you save changes:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ npm run watch
|
||
|
|
```
|
||
|
|
|
||
|
|
As you work your way through the test suite, be sure to remove the `skip <|`
|
||
|
|
calls from each test until you get them all passing!
