I'm trying to programmatically remember an object array but I'm lacking skills and I don't seem to find answers on the web either.
So, I want to be able to, while drawing a cardObj, to remove its reverse(upsidedown) alternative. Note that I wanna do the same if the reverse version is drawer first - remove the upright one from the deck.
Here is the code:
Cardz Exerz! // CARDS OBJECT ------------------------------------------------------------------------------------>
let cardObj = [
{name: "0_Fool", imgUrl: "data/0_Fool.jpg"},
{name: "0_Fool_R", imgUrl: "data/0_Fool_R.jpg"},
//{name: "1_Magician", imgUrl: "data/1_Magician.jpg"},
//{name: "1_Magician_R", imgUrl: "data/1_Magician_R.jpg"},
];
//--- ------------------------------------------------------------------------------------>
//SHUFFLE CARDS ------------------------------------------------------------------------------------>
function shuffle(array){
let currentIndex = array.length, randomIndex;
while(currentIndex != 0){
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex--;
[array[currentIndex], array[randomIndex]] = [array[randomIndex], array[currentIndex]];
}
return array;
};
shuffle(cardObj);
//--- ------------------------------------------------------------------------------------>
//DRAW ------------------------------------------------------------------------------------>
function drawCard(id){
if(cardObj.length === 0){
return;
}
let castCard = document.getElementById(id);
let card = document.createElement('img');
card.setAttribute('src', cardObj[0].imgUrl);
card.setAttribute('height', '272');
card.setAttribute('width', '185');
card.innerHTML = cardObj[0].imgUrl;
if(castCard.id === 'imgPast'){
document.getElementById("btnPast").replaceChild(card, castCard);
}else if(castCard.id === 'imgPresent'){
document.getElementById("btnPresent").replaceChild(card, castCard);
}else if(castCard.id === 'imgFuture'){
document.getElementById("btnFuture").replaceChild(card, castCard);
}
if(cardObj[0].name === cardObj[0].name){
cardObj = cardObj.filter(function(f) {return f !== cardObj.name + "_R"});
}
cardObj.shift();
return false;
}

I am quite confused about your question here but I'll assume what you want is to remove the "opposite" element of the array depending on the card that's drawn.
let cardObj = [
{name: "0_Fool", imgUrl: "data/0_Fool.jpg"},
{name: "0_Fool_R", imgUrl: "data/0_Fool_R.jpg"},
{name: "1_Magician", imgUrl: "data/1_Magician.jpg"},
{name: "1_Magician_R", imgUrl: "data/1_Magician_R.jpg"},
];
function drawCard(id){
if(cardObj.length === 0) return;
// assuming that all 'reverse' cards end with '_R' and that 'id' is the 'name'
const isReverse = id.endsWith('_R');
// construct opposite card ID
const oppositeCardID = isReverse ? id.substring(0, id.lastIndexOf('_')) : (id + '_R');
// Find opposite card index in the array
const oppositeCardIndex = cardObj.findIndex(card => card.name == oppositeCardID);
if (oppositeCardIndex < 0) return; // opposite card not found
// Remove opposite card from deck
cardObj.splice(oppositeCardIndex, 1);
}
console.log("Cards before drawing:", JSON.stringify(cardObj));
console.log("Drawing card 1_Magician");
drawCard("1_Magician");
console.log("Cards after drawing:", JSON.stringify(cardObj));
