A very simple implementation of dependency injection concept for both frontend and backend in ES6.

Usage

const classesConfig = [
    {
        clazz: Engine,
        scope: 'prototype'
    },
    {
        clazz: Car,
        dependencies: [Engine],
        scope: 'prototype'
    },
    {
        clazz: Manufacture
    }
];
const container = new Container(classesConfig);

container.getClass('Engine');
