assign-symbols

Assign the enumerable es6 Symbol properties from an object (or objects) to the first object passed on the arguments. Can be used as a supplement to other extend, assign or merge methods as a polyfill for the Symbols part of the es6 Object.assign method.

From the Mozilla Developer docs for Symbol:

A symbol is a unique and immutable data type and may be used as an identifier for object properties. The symbol object is an implicit object wrapper for the symbol primitive data type.

Install with npm

$ npm i assign-symbols --save

var assignSymbols = require('assign-symbols');
var obj = {};

var one = {};
var symbolOne = Symbol('aaa');
one[symbolOne] = 'bbb';

var two = {};
var symbolTwo = Symbol('ccc');
two[symbolTwo] = 'ddd';

assignSymbols(obj, one, two);

console.log(obj[symbolOne]);
//=> 'bbb'
console.log(obj[symbolTwo]);
//=> 'ddd'
