Lists enumerable own and inherited property keys and symbols of an object.

"fav" is an abbreviation of "favorite" and also the acronym of "for all versions". This package is intended to support all Node.js versions and many browsers as possible. At least, this package supports Node.js >= v0.10 and major Web browsers: Chrome, Firefox, IE11, Edge, Vivaldi and Safari.

Install

To install from npm:

$ npm install --save @fav/prop.enum-all-props

NOTE: npm < 2.7.0 does not support scoped package, but old version Node.js supports it. So when you use such older npm, you should download this package from github.com, and move it in node_modules/@fav/prop.enum-all-props/ directory manually.

Usage

For Node.js:

var enumAllProps = require('@fav/prop.enum-all-props');

var symbol0 = Symbol('foo');
var symbol1 = Symbol('bar');

var obj = { a: 1 };
obj[symbol0] = 2;
Object.defineProperty(obj, 'b', { value: 3 });
Object.defineProperty(obj, symbol1, { value: 4 });

enumAllProps(obj); // => ['a', Symbol(foo) ]

function Fn() { this.a = 1; }
Fn.prototype.b = true;
Fn.prototype[symbol0] = false;
var fn = new Fn();
enumAllProps(fn); // => ['a', 'b', Symbol(foo)]

For Web browsers:

<script src="fav.prop.enum-all-props.min.js"></script>
<script>
var enumAllProps = fav.prop.enumAllProps;

var symbol0 = Symbol('foo');
var symbol1 = Symbol('bar');

var obj = { a: 1 };
obj[symbol0] = 2;
Object.defineProperty(obj, 'b', { value: 3 });
Object.defineProperty(obj, symbol1, { value: 4 });

enumAllProps(obj); // => ['a', Symbol(foo) ]
