# Pangram

Determine if a sentence is a pangram. A pangram (Greek: παν γράμμα, pan gramma,
"every letter") is a sentence using every letter of the alphabet at least once.
The best known English pangram is: 
> The quick brown fox jumps over the lazy dog.

The alphabet used consists of ASCII letters `a` to `z`, inclusive, and is case
insensitive. Input will not contain non-ASCII symbols.

## 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!
