Class Merge
===========
Merge of additional (mixin) Classes into an primary (base) class
About
-----
Class Merge is a very small JavaScript library for Node.js environments,
providing just a single function for use in ECMAScript 6 class
inheritance. It aggregates/merges a base class and one or
more mixin classes into an aggregate class, which then is usually
subsequently used as the base class for another class.
Installation
------------
```shell
$ npm install @uci-utils/class-merge
```
Usage
-----
#### ECMAScript 6
requires using -r esm
```js
import merge from '@uci-utils/class-merge'
class Colored {
initializer () { this._color = "white" }
get color () { return this._color }
set color (v) { this._color = v }
}
class ZCoord {
initializer () { this._z = 0 }
get z () { return this._z }
set z (v) { this._z = v }
}
class Shape {
constructor (x, y) { this._x = x; this._y = y }
get x () { return this._x }
set x (v) { this._x = v }
get y () { return this._y }
set y (v) { this._y = v }
}
class Rectangle extends merge(Shape, Colored, ZCoord) {}
var rect = new Rectangle(7, 42)
rect.z = 1000
rect.color = "red"
