Вызов имени функции и добавленной переменной

Question

Как я могу добавить переменную к имени функции? Будет несколько функций, поэтому я создал счетчик, который увеличивается. После добавления счетчика должна быть выполнена функция newArea1, затем функция newAre2 и т. Д. Я прошу вас о помощи почти весь день. Спасибо заранее за вашу помощь.

    const home = document.querySelector("#home");

Может быть, это поможет: Каждая функция также является методом объекта окна. для вызова нумерованной функции вы можете написать: window["newArea"+counter]()

function newArea1(){
  return "this is newArea1 function";
}

function newArea2(){
  return "this is newArea2 function";
}

let counter = 1;

console.log(window["newArea"+counter]());

counter++;

console.log(window["newArea"+counter]())
