# Pascals Triangle
|
|
|
|
Compute Pascal's triangle up to a given number of rows.
|
|
|
|
In Pascal's Triangle each number is computed by adding the numbers to
|
|
the right and left of the current position in the previous row.

## 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!
