# 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.
