# Allergies
|
||
|
|
||
|
Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.
|
||
|
|
||
|
An allergy test produces a single numeric score which contains the
|
||
|
information about all the allergies the person has (that they were
|
||
|
tested for).
|
||
|
|
||
|
The list of items (and their value) that were tested are:
|
||
|
|
||
|
* eggs (1)
|
||
|
* peanuts (2)
|
||
|
* shellfish (4)
|
||
|
* strawberries (8)
|
||
|
* tomatoes (16)
|
||
|
* chocolate (32)
|
||
|
* pollen (64)
|
||
|
* cats (128)
|
||
|
|
||
|
So if Tom is allergic to peanuts and chocolate, he gets a score of 34.
|
||
|
|
||
|
Now, given just that score of 34, your program should be able to say:
|
||
|
|
||
|
- Whether Tom is allergic to any one of those allergens listed above.
|
||
|
- All the allergens Tom is allergic to.
|
||
|
|
||
|
Note: a given score may include allergens **not** listed above (i.e.
|
||
|
allergens that score 256, 512, 1024, etc.). Your program should
|
||
|
ignore those components of the score. For example, if the allergy
|
||
|
score is 257, your program should only report the eggs (1) allergy.

## 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!
