    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>

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] <!-- [![dependencies][dependencies-image]][dependencies-url] -->

> Test if a value is an [alphagram][alphagram].

<section class="installation">

## Installation

```bash
npm install @stdlib/assert-is-alphagram
```

</section>

<section class="usage">

## Usage

```javascript
var isAlphagram = require( '@stdlib/assert-is-alphagram' );
```

#### isAlphagram( value )

Tests if a `value` is an [alphagram][alphagram] (i.e., a sequence of characters arranged in alphabetical order).

```javascript
var value = 'beep';

var bool = isAlphagram( value );
// returns true
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   The function first checks that an input `value` is a `string` before validating that the `value` is an [alphagram][alphagram]. For non-string values, the function returns `false`.

</section>

<!-- /.notes -->

<section class="examples">

## Examples

<!-- eslint-disable no-new-wrappers -->

<!-- eslint no-undef: "error" -->

```javascript
var isAlphagram = require( '@stdlib/assert-is-alphagram' );

var out = isAlphagram( 'beep' );
// returns true

out = isAlphagram( new String( 'beep' ) );
// returns true

out = isAlphagram( '' );
// returns false

out = isAlphagram( 'zba' );
// returns false

out = isAlphagram( 123 );
// returns false
```
