# Nucleotide Count
Given a DNA string, compute how many times each nucleotide occurs in the string.
DNA is represented by an alphabet of the following symbols: 'A', 'C',
'G', and 'T'.
Each symbol represents a nucleotide, which is a fancy name for the
particular molecules that happen to make up a large part of DNA.
Shortest intro to biochemistry EVAR:
- twigs are to birds nests as
- nucleotides are to DNA and RNA as
- amino acids are to proteins as
- sugar is to starch as
- oh crap lipids
I'm not going to talk about lipids because they're crazy complex.
So back to nucleotides.
DNA contains four types of them: adenine (`A`), cytosine (`C`), guanine
(`G`), and thymine (`T`).
RNA contains a slightly different set of nucleotides, but we don't care
about that for now.
## Setup
Go through the setup instructions for JavaScript to
install the necessary dependencies:
http://exercism.io/languages/javascript
## Making the Test Suite Pass
Execute the tests with:
jasmine <exercise-name>.spec.js
Replace `<exercise-name>` with the name of the current exercise. E.g., to
test the Hello World exercise:
jasmine hello-world.spec.js
In many test suites all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
changing `xit` to `it`.
