A very good W3school tutorial can be found here.

Javascript – setTimeout and setInterval time management

I want to create a function that prints ‘Hello, World!’ every second for 5 minutes, and after 5 minutes, this function will stop for 1 minute. I want to create a loop like this with setTimeout and setInterval, but I couldn’t. Can anyone help me?

const helloWorld = () => console.log("Hello, World!")

const stopSayHello = () => console.log("Stopped for a minute!")

The HelloWorld function will run every second for 5 minutes. After 5 minutes, the stopSayHello function will run for a minute. Then, this loop will continue.

    You can have a function startTimer that will initiate the procedure…

    it will use setInterval to invoke helloWorld each second.. while keeping track of the number of times it occurred. When such counter hits 5*60 (1 minute) it clears the interval and prints it will be waiting for 1 minute.. by doing setTimeout and restarting the whole startTimer after such amount of time.

    The question is: such approach will overflow the call stack? Legit question but the setTimeout is expected to return immediately anwyay so there’s no infinite calls through the stack.

    const helloWorld = () => console.log("Hello, World!")
const stopSayHello = () => console.log("Stopped for a minute!")

var seconds = 0;

var timer;
startTimer();

function startTimer(){
  timer = setInterval(()=>{
    seconds += 1;  
    helloWorld();
    if (seconds == 5*60){
      seconds = 0;
      clearInterval(timer);
      stopSayHello();
      setTimeout(startTimer, 1000*60);
    }
  }, 1000);
}

    Here we go:

    const minutes5 = 300000, minutes1 = 60000, sec1 = 1000;
const printHelloWorld = () {
  console.log('Hello, World!');
}
const stopIntervalTimer = (timerID) => {
    clearInterval(timerID);
}
const run = () {
  // Run the loop for 5 minutes
  const loopIntervalID = setInterval(printHelloWorld, sec1);
  setTimeout(() => {
    // Stop the loop after 5 minutes
    stopIntervalTimer(loopIntervalID);
    console.log('Loop stopped. Waiting for 1 minute...');
    
    // Wait for 1 minute before starting the loop again
    setTimeout(() => {
      console.log('Resuming loop...');
      run();
    }, minutes1);
  }, minutes5);
}

run();

    I add code below.

    const helloWorld = () => console.log("Hello, World!");
const stopSayHello = () => console.log("Stopped for a minute!");

const runLoop = () => {
  let timePassed = 0;

  // Run helloWorld every second until 5 minutes pass
  const helloInterval = setInterval(() => {
    helloWorld();
    timePassed += 1000;

    // After 5 minutes, stop helloWorld and run stopSayHello
    if (timePassed >= 5 * 60 * 1000) {
      clearInterval(helloInterval);
      stopSayHello();

      // After 1 minute, restart the loop
      setTimeout(runLoop, 60 * 1000);
    }
  }, 1000);
};

// Start the loop
runLoop();

    const helloWorld = () => console.log("Hello, World!");
const stopSayHello = () => console.log("Stopped for a minute!");

const runHelloWorld = () => {
  // Run helloWorld every second for 5 minutes
  const helloInterval = setInterval(() => helloWorld(), 1000);
  
  // After 5 minutes, stop saying hello and wait for 1 minute
  setTimeout(() => {
    clearInterval(helloInterval);  // Stop the helloWorld interval
    stopSayHello();               // Print the stop message
    // After 1 minute, restart the loop
    setTimeout(() => runHelloWorld(), 60000);
  }, 300000);  // 5 minutes in milliseconds
};

// Start the loop
runHelloWorld();

    This code sets up an initial setInterval to call the helloWorld function every second. After 5 minutes (300,000 milliseconds), it clears the interval, prints the stop message, and sets a setTimeout to restart the loop after 1 minute (60,000 milliseconds). This process repeats indefinitely.
