```js

const obj = {
get foo() {
return 'foo';
},
bar: {}
};
isAccessor(obj, 'foo'); //=> true
isAccessor(obj, 'bar'); //=> false
// or, if you already have the descriptor you can pass it directly
const foo = Object.getOwnPropertyDescriptor(obj, 'foo');
isAccessor(foo); //=> true
const bar = Object.getOwnPropertyDescriptor(obj, 'bar');
isAccessor(bar); //=> false
