# Resistor Color Duo
2+
3+
If you want to build something using a Raspberry Pi, you'll probably use _resistors_. For this exercise, you need to know two things about them:
4+
5+
* Each resistor has a resistance value.
6+
* Resistors are small - so small in fact that if you printed the resistance value on them, it would be hard to read.
7+
To get around this problem, manufacturers print color-coded bands onto the resistors to denote their resistance values. Each band acts as a digit of a number. For example, if they printed a brown band (value 1) followed by a green band (value 5), it would translate to the number 15.
8+
9+
In this exercise, you are going to create a helpful program so that you don't have to remember the values of the bands. The program will take two colors as input, and output the correct number.
10+
11+
The band colors are encoded as follows:
12+
13+
- Black: 0
14+
- Brown: 1
15+
- Red: 2
16+
- Orange: 3
17+
- Yellow: 4
18+
- Green: 5
19+
- Blue: 6
20+
- Violet: 7
21+
- Grey: 8
22+
- White: 9
23+
24+
## Setup
25+
26+
Go through the setup instructions for Javascript to install the necessary
27+
dependencies:
28+
29+
[https://exercism.io/tracks/javascript/installation](https://exercism.io/tracks/javascript/installation)
30+
31+
## Requirements
32+
33+
Install assignment dependencies:
34+
35+
```bash
36+
$ npm install
37+
```
38+
39+
## Making the test suite pass
40+
41+
Execute the tests with:
42+
43+
```bash
44+
$ npm test
45+
```
46+
47+
In the test suites all tests but the first have been skipped.
48+
49+
Once you get a test passing, you can enable the next one by changing `xtest` to
50+
`test`.

## Submitting Incomplete Solutions
57+
58+
It's possible to submit an incomplete solution so you can see how others have
59+
completed the exercise.
