## Install

To install from npm:

```sh
$ 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][repo-url], and move it in `node_modules/@fav/prop.enum-all-props/` directory manually.*


## Usage

For Node.js:

```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:

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

var symbol0 = Symbol('foo');

Object.defineProperty(obj, 'b', { value: 3 });
