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 anobject
'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' ]
