@stdlib/utils-property-descriptor

About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isAccessorProperty

Test if an object's own property has an accessor descriptor.

Installation

1npm install @stdlib/assert-is-accessor-property

Usage

1var isAccessorProperty = require( '@stdlib/assert-is-accessor-property' );

isAccessorProperty( value, property )

Returns a boolean indicating if an object's own property has an accessor descriptor.

1var defineProperty = require( '@stdlib/utils-define-property' );
2
3var obj = {
4    'foo': 'bar'
5};
6
7defineProperty( obj, 'beep', {
8    'configurable': false,
9    'enumerable': false,
10    'writable': false,
11    'value': 'boop'
12});
13
14defineProperty( obj, 'accessor', {
15    'configurable': false,
16    'enumerable': false,
17    'get': function getter() {
18        return obj.foo;
19    },
20    'set': function setter( v ) {
21        obj.foo = v;
22    }
23});
24
25var bool = isAccessorProperty( obj, 'foo' );
26// returns false
27
28bool = isAccessorProperty( obj, 'beep' );
29// returns false
30
31bool = isAccessorProperty( obj, 'accessor' );
32// returns true

Notes

Value arguments other than null or undefined are coerced to objects.

1var bool = isAccessorProperty( 'beep', 'length' );
2// returns false

Non-symbol property arguments are coerced to strings.

1var defineProperty = require( '@stdlib/utils-define-property' );
2
3var obj = {};
4
5function getter() {
6    return true;
7}
8
9defineProperty( obj, 'null', {
10    'configurable': true,
11    'enumerable': true,
12    'get': getter
13});
14
15var bool = isAccessorProperty( obj, null );
16// returns true

Examples

1var isAccessorProperty = require( '@stdlib/assert-is-accessor-property' );
2
3var bool = isAccessorProperty( [ 'a' ], 'length' );
4// returns false
5
6bool = isAccessorProperty( { 'a': 'b' }, 'a' );
7// returns false
8
9bool = isAccessorProperty( [ 'a' ], 0 );
10// returns false
11
12bool = isAccessorProperty( { 'null': false }, null );
13// returns false
14
15bool = isAccessorProperty( { '[object Object]': false }, {} );
16// returns false
17
18bool = isAccessorProperty( {}, 'toString' );
19// returns false
20
21bool = isAccessorProperty( {}, 'hasOwnProperty' );
22// returns false
23
24bool = isAccessorProperty( null, 'a' );
25// returns false
26
27bool = isAccessorProperty( void 0, 'a' );
28// returns false
