Quick question on for/if

[dan-ator]

In an if/else statement, how do I tell it to just do nothing in the else part? In other words,

function nextButton() {
    if (currentNumber < (cardData.length-1)) {
      currentNumber++;
      drawCard();
    } else {
      alert("You're Done!")
    }
  }

instead of using the alert to say youre done, I want it just not to do anything.

Three backtics for multiple lines of code!

Just omit the else bit:

function nextButton() {
    if (currentNumber < (cardData.length-1)) {
      currentNumber++;
      drawCard();
    }
  }
