I don't understand why my code is not passing

Tell us what’s happening:
Describe your issue in detail here.

  **Your code so far**

var count = 0;

function cc(card) {
// Only change code below this line
if(card >= 2 || card <= 6){
count++;
} else if(card >=7 || card <= 9){
count;
} else if(card = 10 || "J" || "Q" || "K" || "A"){
count--;
}
let holdBet = "Hold";
if(count > 0){
holdBet;
} else{
holdBet = "Bet"

return `${count} ${holdBet}`;
// Only change code above this line
}

cc(2); cc(3); cc(7); cc('K'); cc('A');

You also can’t chain comparisons like that, each expression is independent from the others

This is always true

This is also always true

Okay thank you I get what you are saying.
