properties

Return an array of an object's own enumerable and non-enumerable property names and symbols.

Usage

var properties = require( '@stdlib/utils/properties' );

properties( obj )

Returns an array of an object's own enumerable and non-enumerable property names and symbols.

var obj = {
    'a': 1,
    'b': 2
};

var props = properties( obj );
// e.g., returns [ 'a', 'b' ]

Notes

• Property order is not guaranteed, as object property enumeration is not specified according to the ECMAScript specification. In practice, however, most engines use insertion order to sort an object's properties, thus allowing for deterministic extraction.

Examples

var defineProperty = require( '@stdlib/utils/define-property' );
var properties = require( '@stdlib/utils/properties' );

function Foo() {
    this.beep = 'boop';
    this.a = {
        'b': 'c'
    };
    defineProperty( this, 'baz', {
        'value': 'qux',
        'configurable': true,
        'writable': true,
        'enumerable': false
    });
    return this;
}

Foo.prototype.foo = [ 'bar' ];

var obj = new Foo();
var props = properties( obj );

console.log( props );
// e.g., => [ 'beep', 'a', 'baz' ]
