- # assign-symbols [](http://badge.fury.io/js/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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/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
- Install with [npm](https://www.npmjs.com/)
- ```sh
- $ npm i assign-symbols --save
- ```
- ## Usage
- ```js
- 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'
- ```
