# isMethod

> Test if an object has a specified method name.

<section class="usage">

## Usage

```javascript
var isMethod = require( '@stdlib/assert/is-method' );
```

#### isMethod( value, property )

Returns a `boolean` indicating if a `value` has a specified [**own**][@stdlib/assert/has-own-property] method name.

```javascript
function noop() {
    // Example function...
}

var value = {
    'beep': noop
};

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

bool = isMethod( value, 'toString' );
// returns false
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

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

    ```javascript
    var bool = isMethod( 'beep', 'toString' );
    // returns false
    ```

-   Property arguments are coerced to `strings`.

    ```javascript
    function noop() {
        // Example function...
    }

    var value = {
        'null': noop
    };
    var bool = isMethod( value, null );
    // returns true

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

-   The function searches only [**own**][@stdlib/assert/has-own-property] properties.
