Counting Cards: Trying If-Else

JavaScript
1

Tell us what’s happening:
So, I was trying out something to see if it would work, and as far as I can tell, in theory, if I had done it right I could use If-Else processes as opposed to Switch processes. However, since it didn’t work I either missed something or I don’t understand the If-Else like I thought I did.
I emphasized the part where it says the issue is. thanks!

Your code so far


var count = 0;

function cc(card) {
  // Only change code below this line
   if (card >= 2 && card <= 6){
      count++; }
    *else (card = 10 || card = "J" || card = "Q" || card = "K" || card = "A" ){*
*      count--;*
    } 
    if (count > 0){
        return count + " Bet";
      } else {
        return count + " Hold";
      }
  // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');
