    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="usage">

## Usage

```javascript
var isRangeError = require( '@stdlib/assert-is-range-error' );
```

#### isRangeError( value )

Tests if a `value` is a [`RangeError`][mdn-range-error] object.

```javascript
var bool = isRangeError( new RangeError( 'beep' ) );
// returns true
```

## Notes

-   This function should **not** be considered robust. While the function should **always** return `true` if provided a [`RangeError`][mdn-range-error] (or a descendant) object, false positives may occur due to the fact that the [`RangeError`][mdn-range-error] constructor inherits from [`Error`][mdn-error] and has no internal class of its own. Hence, [`RangeError`][mdn-range-error] impersonation is possible.

## Examples

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

```javascript
var isRangeError = require( '@stdlib/assert-is-range-error' );

var bool = isRangeError( new RangeError( 'range error' ) );
// returns true

bool = isRangeError( new Error( 'error' ) );
// returns false

bool = isRangeError( new EvalError( 'eval error' ) );
// returns false

bool = isRangeError( new ReferenceError( 'reference error' ) );
// returns false

bool = isRangeError( new SyntaxError( 'syntax error' ) );
// returns false

bool = isRangeError( new TypeError( 'type error' ) );
// returns false

bool = isRangeError( new URIError( 'URI error' ) );
// returns false

bool = isRangeError( {} );
// returns false

bool = isRangeError( null );
// returns false
