I'm doing the seven-and-a-half game in JS, for the moment I'm trying to show on the screen when I press a button a random card and its punctuation, that is, the number one will be worth 1 point, the number 2 2 points, so succesivamente, I need a little enough of help. Thanks in advance

You can, more easily and orderly generate your letters like this

function gen() {
var arr = [], max = 20, static = "baralla/basto/carta";
for(let i =1;i<=max;i++){
 arr.push(static+i+".png");
}
return arr;
}

function azar() {
 var all = gen(),
     random = Math.floor(Math.random() * all.length);
     return all[random];
}

console.log('Carta al azar: ${azar()}');
