> Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.
|
||||
|
||||
## Examples
|
||||
|
||||
```js
|
||||
var isAccessor = require('is-accessor-descriptor');
|
||||
var assert = require('assert');
|
||||
|
||||
assert.equal(isAccessor({ get: function() {} }), true);
|
||||
```
|
||||
|
||||
You may also pass an object and property name to check if the property is an accessor:
|
||||
|
||||
```js
|
||||
assert.equal(isAccessor({ bar: {} }, 'bar'), true);
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
`false` when not an object
|
||||
|
||||
```js
|
||||
assert.equal(isAccessor('a'), false);
|
||||
assert.equal(isAccessor(null), false);
|
||||
```
|
||||
|
||||
`true` when the object has valid properties
|
||||
|
||||
and the properties all have the correct JavaScript types:
|
||||
|
||||
```js
|
||||
assert.equal(isAccessor({ get() {}, set() {} }), true);
|
||||
assert.equal(isAccessor({ get() {} }), true);
|
||||
assert.equal(isAccessor({ set() {} }), true);
|
||||
```
|
||||
|
||||
`false` when the object has invalid properties
|
||||
|
||||
```js
|
||||
assert.equal(isAccessor({ get() {}, set() {}, enumerable: 'baz' }), false);
|
||||
assert.equal(isAccessor({ get() {}, writable: true }), false);
|
||||
assert.equal(isAccessor({ get() {}, value: true }), false);
|
||||
```
|
||||
|
||||
`false` when an accessor is not a function
|
||||
|
||||
```js
|
||||
isAccessor({ get() {}, set: 'baz' });
|
||||
isAccessor({ get: 'foo', set() {} });
|
||||
isAccessor({ get: 'foo', bar: 'baz' });
|
||||
isAccessor({ get: 'foo', set: 'baz' });
|
||||
//=> false
|
||||
```
|
||||
|
||||
`false` when a value is not the correct type
|
||||
|
||||
```js
|
||||
isAccessor({ get() {}, set() {}, enumerable: 'foo' });
|
||||
isAccessor({ set() {}, configurable: 'foo' });
|
||||
isAccessor({ get() {}, configurable: 'foo' });
|
||||
//=> false
|
||||
```
