# isAccessorProperty > Test if an object's own property has an accessor descriptor.
## Usage ```javascript var isAccessorProperty = require( '@stdlib/assert/is-accessor-property' ); ``` #### isAccessorProperty( value, property ) Returns a `boolean` indicating if an object's own `property` has an accessor descriptor. ```javascript var defineProperty = require( '@stdlib/utils/define-property' ); var obj = { 'foo': 'bar' }; defineProperty( obj, 'beep', { 'configurable': false, 'enumerable': false, 'writable': false, 'value': 'boop' }); defineProperty( obj, 'accessor', { 'configurable': false, 'enumerable': false, 'get': function getter() { return obj.foo; }, 'set': function setter( v ) { obj.foo = v; } }); var bool = isAccessorProperty( obj, 'foo' ); // returns false bool = isAccessorProperty( obj, 'beep' ); // returns false bool = isAccessorProperty( obj, 'accessor' ); // returns true ```
## Notes - Value arguments other than `null` or `undefined` are coerced to `objects`. ```javascript var bool = isAccessorProperty( 'beep', 'length' ); // returns false ``` - Non-symbol property arguments are coerced to `strings`. ```javascript var defineProperty = require( '@stdlib/utils/define-property' ); var obj = {}; function getter() { return true; } defineProperty( obj, 'null', { 'configurable': true, 'enumerable': true, 'get': getter }); var bool = isAccessorProperty( obj, null ); // returns true ```
## Examples ```javascript var isAccessorProperty = require( '@stdlib/assert/is-accessor-property' ); var bool = isAccessorProperty( [ 'a' ], 'length' ); // returns false bool = isAccessorProperty( { 'a': 'b' }, 'a' ); // returns false bool = isAccessorProperty( [ 'a' ], 0 ); // returns false bool = isAccessorProperty( { 'null': false }, null ); // returns false bool = isAccessorProperty( { '[object Object]': false }, {} ); // returns false bool = isAccessorProperty( {}, 'toString' ); // returns false bool = isAccessorProperty( {}, 'hasOwnProperty' ); // returns false bool = isAccessorProperty( null, 'a' ); // returns false bool = isAccessorProperty( void 0, 'a' ); // returns false ```
