is-accessor-descriptor

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

Examples

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:

assert.equal(isAccessor({ bar: {} }, 'bar'), true);

Examples

false when not an object

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:

assert.equal(isAccessor({ get() {}, set() {} }), true);
assert.equal(isAccessor({ get() {} }), true);
assert.equal(isAccessor({ set() {} }), true);

false when the object has invalid properties

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

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

isAccessor({ get() {}, set() {}, enumerable: 'foo' });
isAccessor({ set() {}, configurable: 'foo' });
isAccessor({ get() {}, configurable: 'foo' });
//=> false
