# Raindrops
2+
3+
Convert a number to a string, the contents of which depend on the number's factors.
4+
5+
- If the number has 3 as a factor, output 'Pling'.
6+
- If the number has 5 as a factor, output 'Plang'.
7+
- If the number has 7 as a factor, output 'Plong'.
8+
- If the number does not have 3, 5, or 7 as a factor,
9+
just pass the number's digits straight through.
10+
11+
## Examples
12+
13+
- 28's factors are 1, 2, 4, **7**, 14, 28.
14+
- In raindrop-speak, this would be a simple "Plong".
15+
- 30's factors are 1, 2, **3**, **5**, 6, 10, 15, 30.
16+
- In raindrop-speak, this would be a "PlingPlang".
17+
- 34 has four factors: 1, 2, 17, and 34.
18+
- In raindrop-speak, this would be "34".
19+
20+
## Setup
21+
22+
Go through the setup instructions for Javascript to install the necessary
23+
dependencies:
24+
25+
[https://exercism.io/tracks/javascript/installation](https://exercism.io/tracks/javascript/installation)
26+
27+
## Requirements
28+
29+
Install assignment dependencies:
30+
31+
```bash
32+
$ npm install
33+
```
34+
35+
## Making the test suite pass
36+
37+
Execute the tests with:
38+
39+
```bash
40+
$ npm test
41+
```
42+
43+
In the test suites all tests but the first have been skipped.
44+
45+
Once you get a test passing, you can enable the next one by changing `xtest` to
46+
`test`.
47+
48+
## Source
49+
50+
A variation on a famous interview question intended to weed out potential candidates. [http://jumpstartlab.com](http://jumpstartlab.com)
51+
52+
## Submitting Incomplete Solutions
53+
54+
It's possible to submit an incomplete solution so you can see how others have
55+
completed the exercise.
