# Примеси в JavaScript

[![Примеси в JavaScript: mixin, extend, Object.assign, class λ-mixin](https://img.youtube.com/vi/NZMrJ2adEyY/0.jpg)](https://www.youtube.com/watch?v=NZMrJ2adEyY)

Tasks:

- see examples

- implement `extend(obj, ...objects)` so keys from objects will be mixed into obj only if it doesn't contain those keys

- implement `wrap(obj, ...funcs)` so if obj contains func.name it should be wrapped

- implement mixin `logable()`

- implement universal `equilateral` mixin for for N sides (see `6-class.js`)

- implement `emitable` with `Object.defineProperty` (see `6-evants.js`)

- implement mixin for prototypes (not instances)

- implement `extend` for mixins with additional `override:Boolean` flag

```js

const mix2 = [

  {

    override: true,

    toString() {

      return `${this.name} - ${this.city} - ${this.born}`;

    }

  },

  {

    override: false,

    age() {

      const year = new Date().getFullYear();

      const born = new Date(this.born).getFullYear();

      return year - born;

    }

  }

];

extend(obj1, mix1, mix2);

```
