+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Usage
+
+```js
+const isDescriptor = require('is-descriptor');
+const assert = require('assert');
+
+assert.equal(isDescriptor({ value: 'foo' }), true);
+assert.equal(isDescriptor({ get() {}, set() {} }), true);
+assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+const obj = { foo: 'abc' };
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+assert.equal(isDescriptor(obj, 'foo'), true);
+assert.equal(isDescriptor(obj, 'bar'), true);
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+assert.equal(isDescriptor('a'), false);
+assert.equal(isDescriptor(null), false);
+assert.equal(isDescriptor([]), false);
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+assert.equal(isDescriptor({ value: 'foo' }), true);
+assert.equal(isDescriptor({ value() {} }), true);
+```
+
+`false` when the object has invalid properties
+
+```js
+assert.equal(isDescriptor({ value: 'foo', enumerable: 'baz' }), false);
+assert.equal(isDescriptor({ value: 'foo', configurable: 'baz' }), false);
+assert.equal(isDescriptor({ value: 'foo', get() {} }), false);
+assert.equal(isDescriptor({ get() {}, value() {} }), false);
+```
+
+`false` when a value is not the correct type
+
+```js
+assert.equal(isDescriptor({ value: 'foo', enumerable: 'foo' }), false);
+assert.equal(isDescriptor({ value: 'foo', configurable: 'foo' }), false);
+assert.equal(isDescriptor({ value: 'foo', writable: 'foo' }), false);
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {} }), true);
+assert.equal(isDescriptor({ get() {} }), true);
+assert.equal(isDescriptor({ set() {} }), true);
+```
+
+`false` when the object has invalid properties
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {}, enumerable: 'baz' }), false);
+assert.equal(isDescriptor({ get() {}, writable: true }), false);
+assert.equal(isDescriptor({ get() {}, value: true }), false);
+```
+
+`false` when an accessor is not a function
+
+```js
+assert.equal(isDescriptor({ get() {}, set: 'baz' }), false);
+assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
+assert.equal(isDescriptor({ get: 'foo', bar: 'baz' }), false);
+assert.equal(isDescriptor({ get: 'foo', set: 'baz' }), false);
+```
+
+`false` when a value is not the correct type
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {}, enumerable: 'foo' }), false);
+assert.equal(isDescriptor({ set() {}, configurable: 'foo' }), false);
+assert.equal(isDescriptor({ get() {}, configurable: 'foo' }), false);
+```
