ECMA Script 6 (ES2015). A weird name that arose from a copyright dispute (European Computer Manufacturing Association).
Standardizing and updating the language is meant to make the lives of developers easier and simpler. Never perfectly aligned across browsers, but does get better over time. ES6 still has some unsupported functionality.

Predictable State Container for Javascript Apps
We dispatch actions (an expression of intent). Redux changes our state for us in a store, and returns a new state. We don't change our state directly. Then we can REWIND TIME.
State: condition of the app (data) at a particular moment in time

Let's make agents to play deterministic zero-sum game.
Monte Carlo tree search is a non-deterministic extension of this approach.
Deterministic games have 'no excuses' (dice rolls, cards drawn etc). Only the players' moves determine the outcome of the game.

react-redux helps us simplify subscribe, unsubscribe, setState, and dispatch by providing us components 'connected' to our store.
It also optimizes our re-renders by diffing our props changes, just like React diffs our virtual and rendered DOM.
Express makes it easy to nest routes in your routers. But I always had trouble accessing the request object's .params when you had a long URI with multiple parameters and nested routes.
Let's say you're building routes for a website www.music.com. Music is organized into albums with multiple tracks. Users can click to see a track list. Then they can select a single track and see a sub-page about that specific track.
At our application level, we could first have a Router to handle any requests to our albums.
const express = require('express');
