    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>

<section class="installation">

## Installation

```bash
npm install @stdlib/string-base-stickycase
```

</section>

<section class="usage">

## Usage

```javascript
var stickycase = require( '@stdlib/string-base-stickycase' );
```

#### stickycase( str\[, p] )

Converts a string to sticky case, where each character in the input string is randomly converted to either uppercase or lowercase.

```javascript
var str = 'hello world';
var out = stickycase( 'hello world' );
// returns <string>
```

By default, the probability for any character to be capitalized is `0.5`. To set a different probability, provide a `p` argument.

```javascript
var str = 'welcome!';
var out = stickycase( 'welcome!', 0.2 );
// returns <string>

str = 'good morning';
out = stickycase( 'good morning', 0.8 );
// returns <string>
```

## Examples

```javascript
var stickycase = require( '@stdlib/string-base-stickycase' );

var str = 'Hello World!';
var out = stickycase( str );
// returns <string>
// returns <string>

str = 'I am a tiny little teapot';
out = stickycase( str );
// returns <string>

str = 'with big problems';
out = stickycase( str, 0.1 );
// returns <string>

str = 'To be, or not to be: that is the question.';
out = stickycase( str, 0.9 );
// returns <string>

str = 'isMobile';
out = stickycase( str );
// returns <string>
