var Boolean = require( '@stdlib/boolean/ctor' );
var Object = require( '@stdlib/object/ctor' );
var isPrimitive = require( '@stdlib/assert/is-primitive' );

var bool = isPrimitive( false );
// returns true

bool = isPrimitive( 0 );
// returns true

bool = isPrimitive( '' );
// returns true

bool = isPrimitive( null );
// returns true

bool = isPrimitive( void 0 );
// returns true

bool = isPrimitive( [] );
// returns false

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

bool = isPrimitive( function noop() {} );
// returns false

bool = isPrimitive( new Boolean() );
// returns false

bool = isPrimitive( new String() );

bool = isPrimitive( new Array() );
