Do you have a question that goes with this code? I know I have some...

There is no question, that i want to ask.
What questions do You have ?


A little fix to the code, for it to look more exciting:


<html><body>

<script>

var y=new Array(2,3,4,5,6,7,8,9,10,'J','Q','K','A','Jo');
var y2=new Array('Hearts','Diamonds','Spade','Clubs');

function y1(a,a2) {
for(var i=Math.round(a/a2)-1; i<=a; i++) {
if((i*a2<=a)&&(a<=(i+1)*a2)) {
return a-i*a2;
break;
}
}
}
function Card() {
var v01=y[y1(Math.round(Math.random()*7458733246324627),y.length)-1]
var v02=y2[y1(Math.round(Math.random()*574354757257835),y2.length)-1];
if(v01=='Jo') return v01;
else return v01+" "+v02;
}

var f1=0;
var f2="";
function f() {
if(f1<5) {
f1++;
setTimeout(function() { f2=f2+" "+Card(); f();}, Math.random()*1517);
} else {
document.write(f2);
}
}
f();

</script>
</body>
</html>

1. Why are you not using array literals?
2. Why do you have a break statement after a return statement
3. Why are you using the numbers '7458733246324627' and '574354757257835' in your array index?
4. Why are some of the entries numbers and others strings?
5. Why are you using document.write?
6. What is going on with that random setTimeout?
7. etc...

I have no question.
Change to code, for it to look more exciting :

 <html><body>

 <script>
 var y=new Array(2,3,4,5,6,7,8,9,10,'J','Q','K','A','Jo');
 var y2=new Array('Hearts','Diamonds','Spade','Clubs');

 function y1(a,a2) {
 for(var i=Math.round(a/a2)-1; i<=a; i++) {
 if((i*a2<=a)&&(a<=(i+1)*a2)) {
 return a-i*a2;
 break;
 }
 }
}
 function Card() {
 var v01=y[y1(Math.round(Math.random()*7458733246324627),y.length)-1]
 var v02=y2[y1(Math.round(Math.random()*574354757257835),y2.length)-1];
 if(v01=='Jo') return v01;
 else return v01+" "+v02;
 }

 var f1=0;
 var f2="";
function f() {
 if(f1<5) {
 f1++;
 setTimeout(function() { f2=f2+" "+Card(); f();}, Math.random()*1426);
 } else {
 document.write(f2);
 }
 }
 f();

 </script>
 </body>
 </html>

All of those from Micheal Haufe, plus

  - Can you think of anything simpler?
  - Have you tried a shuffle?

If I were to try to create a deck, and draw a hand of five cards from it, I might do something like this:

```
// Note that this returns a hand AND mutates the deck by removing those cards

const draw = (n) => (d, i = Math .floor (Math .random () * d .length)) =>
  n == 0 || n > d .length
    ? []
    : [d [i], ...draw (n - 1) (d.splice(i, 1) && d)]

const pokerHand = draw (5)

const deck = ['clubs', 'diamonds', 'hearts', 'spades'] .flatMap (suit => 
  '2-3-4-5-6-7-8-9-10-J-Q-K-A' 
    .split ('-') 
    .map (rank => ({rank, suit}))
)

console .log (pokerHand (deck)) //=>
// [                    // for example
//   {rank: "3", suit: "spades"}, 
//   {rank: "K", suit: "diamonds"},
//   {rank: "A", suit: "diamonds"}, 
//   {rank: "10", suit: "spades"},
//   {rank: "10", suit: "clubs"}
// ]

console .log (deck .length) //=> 47
```

Does this make sense?
