    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/assert-is-anagram
```

</section>

<section class="usage">

## Usage

```javascript
var isAnagram = require( '@stdlib/assert-is-anagram' );
```

#### isAnagram( str, value )

Tests if a `value` is an [anagram][anagram].

```javascript
var str = 'I am a weakish speller';
var value = 'William Shakespeare';

var bool = isAnagram( str, value );
// returns true
```

## Notes

-   The function does **not** address the presence of [diacritics][diacritics].
-   Only **alphanumeric** characters are considered.
-   Capitalization is **ignored**.
-   If provided a non-string for the first `argument`, the function throws an `Error`.
-   If provided a non-string for the second `argument`, the function returns `false`.

## Examples

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

```javascript
var isAnagram = require( '@stdlib/assert-is-anagram' );

var bool = isAnagram( 'I am a weakish speller', 'William Shakespeare' );
// returns true

bool = isAnagram( 'bat', 'tab' );
// returns true

bool = isAnagram( 'bat', 'TAB' );
// returns true

bool = isAnagram( 'bat', 't a b' );
// returns true

bool = isAnagram( 'bat 321', 'tab 123' );
// returns true

bool = isAnagram( 'bat', 'tabba' );
// returns false

bool = isAnagram( 'bat', 5 );
// returns false

bool = isAnagram( '123', 321 );
// returns false
