We are working towards making exercises stand-alone. That is to say: no more generating READMEs on the fly. This will give maintainers more control over each individual exercise README, and it will also make some of the backend logic for delivering exercises simpler. The README template uses the Go text/template package, and the default templates generate the same READMEs as we have been generating on the fly. See the documentation in [regenerating exercise readmes][regenerate-docs] for details. The READMEs can be generated at any time using a new 'generate' command in configlet. This command has not yet landed in master or been released, but can be built from source in the generate-readmes branch on [configlet][].

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 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.
$ npm install
Execute the tests with:
$ npm test
Automatically run tests again when you save changes:
$ 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!

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