Efficient roguelike grid FOV / shadowcasting / line of sight in a single C function inspired by https://docs.microsoft.com/en-us/archive/blogs/ericlippert/shadowcasting-in-c-part-one
// Copyright (c) 2021 Stoiko Todorov
// This work is licensed under the terms of the MIT license.
// For a copy, see https://opensource.org/licenses/MIT.
// What this function does:
// Rasterizes a single Field Of View octant on a grid, similar to the way
// field of view / line of sight / shadowcasting is implemented in some
// roguelikes.
// Uses rays to define visible volumes instead of tracing lines from origin
// to pixels.

Different examples of OOP "class" with "inheritance" done using JavaScript including languages that transpile into js. Take notice to the amount of boilerplate that's needed in ES5 compared to ES6. These examples all have the same interface with pros/cons for each pattern. If they seem similar that's whole point especially the difference between…
var EventEmitter = require('events').EventEmitter;
var _ = require('lodash');
// Factory shared
var makePerson = function() {
var person = {};
EventEmitter.call(person);
person.wallet = 0;
_.extend(person, personMethods)
return person;
