How does this function receive and process values so many times?

Tell us what’s happening:

The code is ok, but I can’t understand how the function will receive a value for the variable many times without a loop structure… could someoen help me? i am novice in javascript

Your code so far


var count = 0;

function cc(card) {
 // Only change code below this line

switch(card) {
   case 2:
   case 3:
   case 4:
   case 5:
   case 6:
     count++;
     break;
   case 10:
   case "J":
   case "Q":
   case "K":
   case "A":
     count--;
     break;
 }

 var holdbet = 'Hold'
 if (count > 0) {
   holdbet = 'Bet'
 }


return count + " " + holdbet;


 // 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');

The test runner calls the function multiple times: https://github.com/freeCodeCamp/freeCodeCamp/blob/master/curriculum/challenges/english/02-javascript-algorithms-and-data-structures/basic-javascript/counting-cards.english.md#tests

here you have five function calls (last line of code), so the function runs five times
for each test there are multiple function calls
