# isBoxedPrimitive
> Test if a value is a JavaScript boxed primitive.
## Usage
```javascript
var isBoxedPrimitive = require( '@stdlib/assert/is-boxed-primitive' );
```
#### isBoxedPrimitive( value )
Tests if a `value` is a JavaScript boxed primitive.
```javascript
var bool = isBoxedPrimitive( new Boolean( false ) );
// returns true
bool = isBoxedPrimitive( true );
// returns false
```
## Notes
- Boxed primitive objects can be created with one of the following:
- `new Boolean()`
- `new Number()`
- `new String()`
- `Object( Symbol() )` (ES6/ES2015)
## Examples
```javascript
var Number = require( '@stdlib/number/ctor' );
var isBoxedPrimitive = require( '@stdlib/assert/is-boxed-primitive' );
var bool = isBoxedPrimitive( new Boolean( false ) );
// returns true
bool = isBoxedPrimitive( new String( 'beep' ) );
// returns true
bool = isBoxedPrimitive( new Number( 3.14 ) );
// returns true
bool = isBoxedPrimitive( false );
// returns false
bool = isBoxedPrimitive( 0 );
// returns false
bool = isBoxedPrimitive( '' );
// returns false
bool = isBoxedPrimitive( null );
// returns false
bool = isBoxedPrimitive( void 0 );
// returns false
bool = isBoxedPrimitive( [] );
// returns false
bool = isBoxedPrimitive( {} );
// returns false
```
