Implementation

There are actually two ways for generating fixtures:

1. Using generateRandomFixture. It will return only one random fixture

const { generateRandomFixture } = require('.fixtureGenerator.js')

/*
    @param  {Array}     array   The array containing all the attendees
*/
const tournaments = generateRandomFixture([1,2,3,4])

console.log(tournaments)

/*
    [
        {
          name: "MatchDay 1",
          value: [
            {
              teamA: 1,
              teamB: 3,
            },
            {
              teamA: 2,
              teamB: 4,
            },
          ],
        },
        {
          name: "MatchDay 2",
          value: [
            {
              teamA: 1,
              teamB: 2,
            },
            {
              teamA: 4,
              teamB: 3,
            },
          ],
        },
        {
          name: "MatchDay 3",
          value: [
            {
              teamA: 1,
              teamB: 4,
            },
            {
              teamA: 3,
              teamB: 2,
            },
          ],
        }
    ]
*/

2. generateRandomFixtureFromAllPermutations takes as argument the number of fixtures you want to generate.

const { generateRandomFixtureFromAllPermutations } = require('.fixtureGenerator.js')

/*
    @param  {Array}     array   The array containing all the attendees
    @param  {Number}    n       The number of tournaments that needs to be randomly generated 
*/
const tournaments = generateRandomFixtureFromAllPermutations([1,2,3,4], 2)

console.log(tournaments)

/*
    // First calendar
    [.....],
    // Second calendar
    [
        {
          name: "MatchDay 1",
          value: [
            {
              teamA: 1,
              teamB: 3,
            },
            {
              teamA: 2,
              teamB: 4,
            },
          ],
        },
        {
          name: "MatchDay 2",
          value: [
            {
              teamA: 1,
              teamB: 2,
            },
            {
              teamA: 4,
              teamB: 3,
            },
          ],
        },
        {
          name: "MatchDay 3",
          value: [
            {
              teamA: 1,
              teamB: 4,
            },
            {
              teamA: 3,
              teamB: 2,
            },
          ],
        }
    ]
