How can I finish a setInterval?

Question

Hello, I wonder if it is possible to stop a setinterval after a certain time, if possible, as?

Answer 1

It is possible, you will need to work with the clearInterval function.

let qtd = 0;

let interval = setInterval( () => {
  console.log("Entrando...");
  qtd++;

  if (qtd == 5) {
    clearInterval(interval);
  }
}, 1000 );

Answer 2

Only use clearInterval() Example:

var myVar = setInterval(myTimer, 1000);

function myTimer() {
  var d = new Date();
  var t = d.toLocaleTimeString();
  document.getElementById("demo").innerHTML = t;
}

function myStopFunction() {
  clearInterval(myVar);
}
