Compose

Basic object composer.

Example

This is a very basic object composer used to create prototype used as class.

• calling compose() returns a composite
• Every call to compose() create a new composite (immutability)
• A composite is a JavaScript object with two main methods: compose & create
• constructor methods are combined together
• The create method of a composite create and returns an instance of the composite

import compose from '@jsenv/compose';

const User = compose({
	constructor() {
		this.items = [];
	}
});
const CompositeUser = User.compose({
	constructor() {
		this.items.push({name: 'sword'});
	}
});

const compositeUser = CompositeUser.create();
compositeUser.items[0].name; // 'sword'
Object.getPrototypeOf(compositeUser) === CompositeUser; // true
