Счетчик сильно увеличивается (Javascript)

Question

У меня есть значение счетчика, которое не может быть расширено как положено. Этот счетчик должен увеличиваться после вызова каждой функции newArea. Однако после вызова первой функции из значения по умолчанию, установленного для counter = 1, counter = 2 завершается, но затем после вызова второй функции значение счетчика внезапно становится равным 5.

Ниже приведен исходный код. Заранее благодарю за помощь.

const home = document.querySelector("#home");
const nickName = document.querySelector(".nick-name");
const startBtn = document.querySelector(".startBtn");
const info = document.querySelector(".info");
let nickArea = document.querySelector(".nick-area");
let moneyArea = document.querySelector(".money-area");
const amountMoney = document.getElementById("amount-money");
const sendBtn = document.getElementById("send-money");
const infoWin = document.querySelector(".info-win");
const gameArea = document.getElementById("game-area");
const amoutWin = document.getElementById("amountwin");
let winArea = document.querySelector(".mywin");
const receive = document.getElementById("receive");
const area = document.querySelector(".area");
const endGameArea = document.getElementById("endgame");
const resetGame = document.getElementById("resetGame");
let currentFunds = 0;
let counter = 0;

//Investors
const InvestorNameArea = document.querySelector(".investor-name h2");
const InvestorPhotoArea = document.querySelector(".investor-image img");
const InvestorDealArea = document.querySelector(".investor-image p");
const Investors = [{name: "Bill Gates", photo: "img/investors/billgates.jpg", deal: "Lorem ipsum dolor sit amet consectetur adipisicing elit.

Answer 1

Ваша переменная счетчика будет увеличена только при нажатии кнопки # send-money:

sendBtn.addEventListener("click", function() {
    sendMoney(nick, currentFunds);
    counter++;
    console.log(counter);
});

Однако к этой кнопке прикреплены прослушиватели с несколькими щелчками мыши. Следовательно, при нажатии на него счетчик будет увеличиваться в несколько раз:

const newArea = (nick) => {
    endGameArea.style = "display: none";
    endGameArea.style = "display: none";
    ...
    sendBtn.addEventListener("click", function() {
        ...
    });
}

потому что newArea также вызывается несколько раз.

Надеюсь, это поможет
