    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/nlp-tokenize
```

</section>

<section class="usage">

## Usage

```javascript
var tokenize = require( '@stdlib/nlp-tokenize' );
```

#### tokenize( str\[, keepWhitespace] )

Tokenizes a string.

```javascript
var str = 'Hello Mrs. Maple, could you call me back?';
var out = tokenize( str );
// returns  [ 'Hello', 'Mrs.', 'Maple', ',', 'could', 'you', 'call', 'me', 'back', '?' ]
```

To include whitespace characters (spaces, tabs, line breaks) in the output array, set `keepWhitespace` to `true`.

```javascript
var str = 'Hello World!\n';
var out = tokenize( str, true );
// returns  [ 'Hello', ' ', 'World', '!', '\n' ]
```
