    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>

## Usage

```javascript
var isSortedAscending = require( '@stdlib/array-base-assert-is-sorted-ascending' );
```

#### isSortedAscending( x )

Tests if an array is sorted in ascending order.

```javascript
var out = isSortedAscending( [ 1, 2, 3 ] );
// returns true

out = isSortedAscending( [ 3, 2, 1 ] );
// returns false
```

If provided an empty array, the function returns `false`.

```javascript
var out = isSortedAscending( [] );
// returns false
```
