Question

How to execute a function repeatedly at specified time intervals (repeating timer) in JavaScript

Answer 1

const intervalId = setInterval(() => {
  console.log("This message appears every 2 seconds!");
}, 2000); // 2000ms = 2 seconds

// To stop the time interval:
setTimeout(() => {
  clearInterval(intervalId);
  console.log("Interval stopped!");
}, 10000); // Stops after 10 seconds



/*
run:

This message appears every 2 seconds!
This message appears every 2 seconds!
This message appears every 2 seconds!
This message appears every 2 seconds!
Interval stopped!
