How to Tell setInterval to Only Fire x Amount of Times with JavaScript?

To tell setInterval to only fire x amount of times with JavaScript, we can keep track of the number of times the setInterval callback is called.

Then when the limit is reached, we can call clearInterval to stop the setInterval timer.

For instance, we can write:

let x = 0;  
const intervalID = setInterval(() => {  
  if (++x === 5) {  
    window.clearInterval(intervalID);  
  }  
  console.log('hello')  
}, 200);

to keep track of the number of times the setInterval callback is called with x .

Then we call setInterval with a callback that increments x with ++ in front to return the value of x after incrementing by 1.

Next, we check if x is 5 to top the timer with clearInterval when the setInterval callback has been called 5 times.

clearInterval is called with the intervalID to stop the timer.

And then we call console log to log some message.

200 is the number of milliseconds between each setInterval call.

As a result, the setInterval callback will be called 5 times only.
