    Lists enumerable own and inherited property 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-symbols

    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-symbols/ directory manually.

    Usage

    For Node.js:

    var enumAllSymbols = require('@fav/prop.enum-all-symbols');
    
    var symbol = Symbol('foo');
    var obj0 = {}, obj1 = {}, obj2 = {};
    
    obj0[symbol] = 123;
    enumAllSymbols(obj0); // => [ Symbol(foo) ]
    
    Object.defineProperty(obj1, symbol, { value: 1 });
    enumAllSymbols(obj1); // => []
    
    var Fn2 = function() {}
    Fn2.prototype = obj0;
    var fn2 = new Fn2();
    fn2[symbol]; // => 123
    enumAllSymbols(fn2); // => [ Symbol(foo) ]

    For Web browsers:

    <script src="fav.prop.enum-all-keys.min.js"></script>
    <script>
    var enumAllSymbols = fav.prop.enumAllSymbols;
    var symbol = Symbol('foo');
    
    obj0[symbol] = 123;
    enumAllSymbols(obj0); // => [ Symbol(foo) ]
    </script>
