JavaScript object hierarchy

This document aims to explain what various attributes like constructor, prototype and __proto__ point to and what happens when new objects are created.

There are several ways of creating new objects:

o = {'one': 1, 'two': 2};
function f() {return 'three';}

Solution to OpenAI Gym CartPole-v0 using hill climbing

Problem statement

https://gym.openai.com/envs/CartPole-v0

A pole is attached by an un-actuated joint to a cart, which moves along a frictionless track. The system is controlled by applying a force of +1 or -1 to the cart. The pendulum starts upright, and the goal is to prevent it from falling over. A reward of +1 is provided for every timestep that the pole remains upright.
