# isBooleanArray
> Test if a value is a [`BooleanArray`][@stdlib/array/bool].
## Usage
```javascript
var isBooleanArray = require( '@stdlib/array/base/assert/is-booleanarray' );
```
#### isBooleanArray( value )
Tests if a value is a [`BooleanArray`][@stdlib/array/bool].
```javascript
var BooleanArray = require( '@stdlib/array/bool' );
var arr = new BooleanArray( 10 );
var bool = isBooleanArray( arr );
// returns true
```
## Notes
- This function is not robust and that is intentional. This function provides a lower cost way to reasonably determine whether an input value is a [`BooleanArray`][@stdlib/array/bool] in order to avoid walking the prototype chain and resolving constructors, which is necessary for robust identification of cross-realm instances. For more robust validation, see [`@stdlib/assert/is-booleanarray`][@stdlib/assert/is-booleanarray].
## Examples
```javascript
var Int8Array = require( '@stdlib/array/int8' );
var Uint8Array = require( '@stdlib/array/uint8' );
var Uint8ClampedArray = require( '@stdlib/array/uint8c' );
var Int16Array = require( '@stdlib/array/int16' );
var Uint16Array = require( '@stdlib/array/uint16' );
var Int32Array = require( '@stdlib/array/int32' );
var Uint32Array = require( '@stdlib/array/uint32' );
var Float32Array = require( '@stdlib/array/float32' );
var Float64Array = require( '@stdlib/array/float64' );
var Complex128Array = require( '@stdlib/array/complex128' );
var Complex64Array = require( '@stdlib/array/complex64' );
var BooleanArray = require( '@stdlib/array/bool' );
var isBooleanArray = require( '@stdlib/array/base/assert/is-booleanarray' );
var bool = isBooleanArray( new BooleanArray( 10 ) );
// returns true
bool = isBooleanArray( new Complex64Array( 10 ) );
// returns false
bool = isBooleanArray( new Complex128Array( 10 ) );
// returns false
bool = isBooleanArray( [] );
// returns false
bool = isBooleanArray( new Float64Array( 10 ) );
// returns false
bool = isBooleanArray( new Float32Array( 10 ) );
// returns false
bool = isBooleanArray( new Int32Array( 10 ) );
// returns false
bool = isBooleanArray( new Uint32Array( 10 ) );
// returns false
bool = isBooleanArray( new Int16Array( 10 ) );
// returns false
bool = isBooleanArray( new Uint16Array( 10 ) );
// returns false
bool = isBooleanArray( new Int8Array( 10 ) );
// returns false
bool = isBooleanArray( new Uint8Array( 10 ) );
// returns false
bool = isBooleanArray( new Uint8ClampedArray( 10 ) );
// returns false
bool = isBooleanArray( { 'length': 0 } );
// returns false
