AEC is a node.js library for dealing with Elo calculation

Installation

Use the package manager node.js to install AEC.

npm install advanced-elo.calculator

Usage

In node.js, just require the module:

const aec = require('advanced-elo.calculator')

There are 4 functions in V 0.1.3:

// Used for 1v1s
aec.c1v1();

// Used for 2v2s
aec.c2v2();

// Used for 3v3s
aec.c3v3();

// User for 4v4s
aec.c4v4();

To use a function, do the folowing:

aec.c1v1(/* Rating Player 1, Rating Player 2, Max. amount of Elo per game (K), Result (0: Lost, 0.5: Draw, 1: Win') (S)*/);

// The result has to be an integer between 0 and 1. Anything over/under does not work

Here are some examples:

console.log(aec.c2v2( /* Team 1 */ 1000, 1050, /* Team 2 */ 1020, 1432, /* K */ 16, /* S */ 0.5))

// Expected Result:
[
  1004.17,            // New Rating from Player 1                        [0]
