## 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.
