How to assign a variable that passed a conditional statement-CodePudding

I have an app that is essentially a random number gen and assigns it to some horse breeds. I need to have a condition that checks if ANY variable AND only 1 variable is equal to 1.

I want something like this that assigns the value that is passed to a variable and then checks it to a user-inputted variable

I tried to mockup something like this, but it seems to only pass boolean results

var balance = ''
var target = getText("horseIn")
var leverage = getNumber("levIn")
var horses = {
    Appaloosa: getNumber("h1pos"),
    frenchTrotter: getNumber("h2pos"),
    Fresian: getNumber("h3pos"),
    Hackney: getNumber("h4pos"),
    Faflinger: getNumber("h5pos"),
    pasoFino: getNumber("h6pos"),
}
var winner = null;
onEvent("startM", "click", function( ) {
  setScreen("selectAmount");
});


onEvent("submitBet", "click", function( ) {
  if (getNumber("userAmount") >0){
    setScreen("horseScreen");
    updateScreen();
    console.log(horses)
    while (winner == null) {
      for (i in horses) {
        if (horses[i] == 1){
          winner = i;
        }
      }
    }
  } else {
    setText("userAmount","Please input an amount!");
  }
  console.log(winner)
});

function updateScreen(){
  setText("h1pos", Math.floor(Math.random() * 6)   1);
  setText("h2pos", Math.floor(Math.random() * 6)   1);
  setText("h3pos", Math.floor(Math.random() * 6)   1);
  setText("h4pos", Math.floor(Math.random() * 6)   1);
  setText("h5pos", Math.floor(Math.random() * 6)   1);
  setText("h6pos", Math.floor(Math.random() * 6)   1);
}

function pnl(){
  setScreen("endScreen");
  if (target == winner) {
    console.log("Winner");
}
}

I am setting the variables like this:

let Appaloosa = Math.floor(Math.random() * 6)   1;
let frenchTrotter = Math.floor(Math.random() * 6)   1;
let Fresian = Math.floor(Math.random() * 6)   1;
let Hackney = Math.floor(Math.random() * 6)   1;
let Faflinger = Math.floor(Math.random() * 6)   1;
let pasoFino = Math.floor(Math.random() * 6)   1;

so I need to repeat the process if none of them work.

I understand you need to get a random name based on some of them wich condition equals 1, you can accomplish this with a simple recursion.

function getWinnerHorse() {
  const horses = {
    Appaloosa: 1 === Math.floor(Math.random() * 6)   1,
    "French Trotter": 1 === Math.floor(Math.random() * 6)   1,
    Fresian: 1 === Math.floor(Math.random() * 6)   1,
    Hackney: 1 === Math.floor(Math.random() * 6)   1,
    Faflinger: 1 === Math.floor(Math.random() * 6)   1,
    "Paso Fino": 1 === Math.floor(Math.random() * 6)   1,
  };

  const horse = Object.entries(horses).find((item) => item[1]);
  if (!horse) return getWinnerHorse();
  return horse[0];
}

console.log(getWinnerHorse());

Hope it helps.

The following code configures a result array object. Arrays are objects with nonnegative integer-like keys.

So we enumerate the competitors and push result positions calculated at random into the arrays corresponding to those positions.

Confirming the winner is as simple as reading position 1 in the array (and checking there is only one entry).

const getPosition = (entrantCount = 0) => Math.floor(Math.random() * entrantCount)   1
const race = (entrants) => 
    entrants.reduce((acc, entrant) => (acc[getPosition(entrants.length)].push(entrant), acc), [...Array(entrants.length 1)].map(() => []))

const raceUntilAWinner = async (entrants) => {
    const result = race(entrants)
    if(result[1]?.length === 1) return result
    return raceUntilAWinner(entrants)
}

;(async () => {
    const entrants = ['Appaloosa', 'French Trotter', 'Fresian', 'Hackney', 'Faflinger']
    const result = await raceUntilAWinner(entrants)
    console.log(`The winner is ${result[1]}.`)
})()
