> Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.

## Examples

```js
const isAccessorDescriptor = require('is-accessor-descriptor');
const assert = require('assert');

const obj = {
	get foo() {},
	bar: { get: function() {} }
};

assert.equal(true, isAccessorDescriptor(obj, 'foo'));
assert.equal(false, isAccessorDescriptor(obj, 'bar'));

// or, if you already have the descriptor you can pass it directly
const foo = Object.getOwnPropertyDescriptor(obj, 'foo');
assert.equal(true, isAccessorDescriptor(foo));

const bar = Object.getOwnPropertyDescriptor(obj, 'bar');
assert.equal(false, isAccessorDescriptor(bar));
```
