    found the solution

    code runs every 2 seconds and after 10 seconds it stops

      function example(){
    var thisinterval = setInterval(() => {
        console.log("testing")
        setTimeout(() => {
            clearInterval(thisinterval)
        }, 10*1000);
    }, 2*1000);
}

    To do this, we can use Promise and setTimeout.

    First, we need to make the Promise by wrapping the API call with it. This will tell the code to wait for the response and continue when it’s ready, or stop if there’s a problem or it takes too long.

    for (let i = 0; i < iterations; i++) {
  const promise = makeAPICall();
  const timeout = setTimeout(() => {
    reject(new Error('Response took too long'));
  }, 5000);
    
  promise.then((response) => {

    clearTimeout(timeout);

    break;
  }).catch((error) => {

    clearTimeout(timeout);

  });
}

    This way, if the API call takes longer than 5 seconds, the promise will be rejected, the timeout will be cleared, and the for loop will continue to the next iteration.
