Counting Cards i don't understand the process, please i need help

Tell us what’s happening:
can someone please help me i don’t understand the whole challenge

Your code so far

var count = 0;

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



  return "Change Me";
  // 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');

Link to the challenge:

You run the same function several times which affects the global variable.
So you control what happens to the count depending on the card.
Note that different “cards” or inputs would produce a different result.

so whats the next step how do i proceed?

Well, you already started your switch statement. Now you need to add the different cases inside of it for each card that could be passed in, with appropriate actions for each case. Because multiple cases will prompt the same action (e.g. cards 2, 3, 4, 5, 6 all need to increment the count) you can combine them.
