# Series

Given a string of digits, output all the contiguous substrings of length `n` in
that string.

For example, the string "49142" has the following 3-digit series:

- 491
- 914
- 142

And the following 4-digit series:

- 4914
- 9142

And if you ask for a 6-digit series from a 5-digit string, you deserve
whatever you get.

Note that these series are only required to occupy *adjacent positions*
in the input; the digits need not be *numerically consecutive*.

## Setup

Go through the setup instructions for JavaScript to install the
 necessary dependencies:

http://exercism.io/languages/javascript/installation

## Running the test suite

The provided test suite uses [Jasmine](https://jasmine.github.io/).
You can install it by opening a terminal window and running the
following command:

```sh
npm install -g jasmine
```

Run the test suite from the exercise directory with:

```sh
jasmine series.spec.js
```

In many test suites all but the first test have been marked "pending".
Once you get a test passing, activate the next one by changing `xit` to `it`.
