# isReadWriteProperty
> Test if an object's own property is readable and writable.
<section class="usage">
## Usage
```javascript
var isReadWriteProperty = require( '@stdlib/assert/is-read-write-property' );
```
#### isReadWriteProperty( value, property )
Returns a `boolean` indicating if a `value` has a readable **and** writable `property`.
<!-- eslint-disable no-restricted-syntax -->
```javascript
var defineProperty = require( '@stdlib/utils/define-property' );
var obj = {
'foo': 'bar'
};
defineProperty( obj, 'beep', {
'configurable': false,
'enumerable': false,
'writable': true,
'value': 'boop'
});
defineProperty( obj, 'accessor', {
'configurable': false,
'enumerable': false,
'get': function getter() {
return obj.foo;
},
'set': function setter( v ) {
obj.foo = v;
}
});
var bool = isReadWriteProperty( obj, 'foo' );
// returns true
bool = isReadWriteProperty( obj, 'beep' );
// returns true
bool = isReadWriteProperty( obj, 'accessor' );
// returns true
```
</section>
<!-- /.usage -->
<section class="notes">
## Notes
- Value arguments other than `null` or `undefined` are coerced to `objects`.
```javascript
var bool = isReadWriteProperty( 'beep', 'length' );
// returns false
```
- Property arguments are coerced to `strings`.
```javascript
var obj = {
'null': 'foo'
};
var bool = isReadWriteProperty( obj, null );
// returns true
```

## Examples
<!-- eslint-disable object-curly-newline -->
<!-- eslint no-undef: "error" -->
```javascript
var isReadWriteProperty = require( '@stdlib/assert/is-read-write-property' );
var bool = isReadWriteProperty( [ 'a' ], 'length' );
// returns true
bool = isReadWriteProperty( { 'a': 'b' }, 'a' );
// returns true
bool = isReadWriteProperty( [ 'a' ], 0 );
// returns true
bool = isReadWriteProperty( { 'null': false }, null );
// returns true
bool = isReadWriteProperty( { '[object Object]': false }, {} );
// returns true
bool = isReadWriteProperty( {}, 'toString' );
// returns false
bool = isReadWriteProperty( {}, 'hasOwnProperty' );
// returns false
bool = isReadWriteProperty( null, 'a' );
// returns false
bool = isReadWriteProperty( void 0, 'a' );
// returns false
