I want to split 52 cards into 26 cards like playing 2 Players. Need to spilt the 52 card for 2 players. I tried all the way but not working for me. I hereby attached HTML, CSS and JS.

Kindly help regarding the same.

var cards = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"];
var suits = ["diamonds", "hearts", "spades", "clubs"];
var deck = new Array();

function getDeck()
{
    var deck = new Array();
    
    for(var i = 0; i < suits.length; i  )
    {
        for(var x = 0; x < cards.length; x  )
        {
            var card = {Value: cards[x], Suit: suits[i]};
            deck.push(card);
        }
    }
    return deck;
}

function shuffle()
{
    // for 1000 turns
    // switch the values of two random cards
    for (var i = 0; i < 1000; i  )
    {
        var location1 = Math.floor((Math.random() * deck.length));
        var location2 = Math.floor((Math.random() * deck.length));
        var tmp = deck[location1];

        deck[location1] = deck[location2];
        deck[location2] = tmp;
    }

    renderDeck();
}

function renderDeck()
{
    document.getElementById('deck').innerHTML = '';
    for(var i = 0; i < deck.length; i  )
    {
        var card = document.createElement("div");

    shuffle();
    renderDeck();
}

window.onload = load;
function split()

const list = cards()
const half = Math.ceil(list.length / 2);

You can try it :

const cards = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"]
const suits = ["diamonds", "hearts", "spades", "clubs"]
let player1 = player2 = []
let deck = cards.reduce((res, card) => [...res, ...suits.map(suit => ({Value: card, Suit: suit}))], [])
const deckEle = document.getElementById('deck')
const deckplayer1 = document.getElementById('player1')
const deckplayer2 = document.getElementById('player2')
const shuffle = () => {
  let currentIndex = deck.length,  randomIndex
  while (currentIndex != 0) {
    randomIndex = Math.floor(Math.random() * currentIndex)
    currentIndex--
    [deck[currentIndex], deck[randomIndex]] = [deck[randomIndex], deck[currentIndex]]
  }
  deckplayer1.innerHTML = ''
  deckplayer2.innerHTML = ''
  renderDeck(deckEle, deck)
}

const renderDeck = (div, arr) => {
    div.innerHTML = ''
    for(let i = 0; i < arr.length; i  )
    {
        let card = document.createElement("div")
        let value = document.createElement("div")

        value.className = "value"
        suit.className = "suit "   arr[i].Suit

        value.innerHTML = arr[i].Value
        card.appendChild(value)

There are a few problems in your code, but for the specific problem you are asking, this line is the problem:

const list = cards()

Your cards variable is not a callable function, it's an array. You cannot call it by cards().

You want this:

const list = cards

But cards is not a list of 52 cards, but a list from Ace to K. Your deck is deck, so you really just want:

const list = deck

var cards = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"];
var suits = ["diamonds", "hearts", "spades", "clubs"];
var deck = new Array();

function getDeck()
{
    var deck = new Array();
    
    for(var i = 0; i < suits.length; i  )
    {
        for(var x = 0; x < cards.length; x  )
        {
            var card = {Value: cards[x], Suit: suits[i]};
            deck.push(card);
        }
    }
    return deck;
}

function shuffle()
{
    // for 1000 turns
    // switch the values of two random cards
    for (var i = 0; i < 1000; i  )
    {
        var location1 = Math.floor((Math.random() * deck.length));
        var location2 = Math.floor((Math.random() * deck.length));
        var tmp = deck[location1];

        deck[location1] = deck[location2];
        deck[location2] = tmp;
    }

    renderDeck();
}

function renderDeck()
{
    document.getElementById('deck').innerHTML = '';
    for(var i = 0; i < deck.length; i  )
    {
        var card = document.createElement("div");
        var value = document.createElement("div");
        var suit = document.createElement("div");
        card.className = "card";
        value.className = "value";
        suit.className = "suit "   deck[i].Suit;

        value.innerHTML = deck[i].Value;
        card.appendChild(value);
        card.appendChild(suit);

        document.getElementById("deck").appendChild(card);
    }
