# hasProperty

> Test if an object has a specified property, either own or inherited.

<section class="usage">

## Usage

```javascript
var hasProp = require( '@stdlib/assert/has-property' );
```

#### hasProp( value, property )

Returns a `boolean` indicating if a `value` has a specified `property`, either own or inherited.

```javascript
var value = {
    'beep': 'boop'
};

var bool = hasProp( value, 'beep' );
// returns true

bool = hasProp( value, 'hasOwnProperty' );
// returns true

bool = hasProp( value, 'bap' );
// returns false
```

## Notes

-   The function does **not** throw when provided `null` or `undefined`. Instead, the function returns `false`.

    ```javascript
    var bool = hasProp( null, 'a' );
    // returns false

    bool = hasProp( void 0, 'a' );
    // returns false
    ```

-   Value arguments other than `null` or `undefined` are coerced to `objects`.

    ```javascript
    var bool = hasProp( 'beep', 'length' );
    // returns true
    ```

-   Non-symbol property arguments are coerced to `strings`.

    ```javascript
    var value = {
        'null': false
    };
    var bool = hasProp( value, null );
    // returns true

    value = {
        '[object Object]': false
    };
    bool = hasProp( value, {} );
    // returns true
    ```
