To remedy this, you can form a fresh array without duplicates or filter while accessing the array.
One approach is to use a Set
const container = document.getElementById("container");
const arr = [1, 2, 3, 3, 3, 3];
const dedup = [...new Set(arr)];
console.log(dedup)
// here all hidden elements are displayed
container.innerHTML = arr.map(item => `<span data-id="${item}" hidden>${item}</span>`).join("")
// and show only the first unique element
dedup.forEach(unique => document.querySelector(`[data-id="${unique}"]`).hidden = false)#container span {
border: 1px solid black;
padding: 2px;
