Change setInterval value dynamically

Question

I want to change interval value of setInterval dynamically. I\'m struggling due to presence of a loop in setInterval callback function. I have seen too many questions on stackov

Answer 1

Here's another easy way to dynamically update interval.

var intv_sec = 1500; // Initial interval in milliseconds
var speed = 1.5; // Multiplier

function chk_fn(){
  // Your code here
  console.log(intv_sec);
  
  
  // Reset and update interval
  clearInterval(chkh);
  intv_sec = intv_sec*speed;
  chkh = setInterval(chk_fn, intv_sec);
}

var chkh = setInterval(chk_fn, intv_sec);
