How Can I Dynamically Change the Interval of `setInterval` in JavaScript?

Modifying the Interval of setInterval During Execution

The setInterval method facilitates repeated execution of a function at a specified interval. However, if you need to dynamically adjust this interval while the function is running, certain challenges arise.

In the example provided, you attempted to modify the interval using the following line:

var interval = setInterval(function() { ... }, 10*counter);

However, this approach failed because the value of 10*counter was evaluating to 0. To address this issue, you could employ an anonymous function, as illustrated below:

var counter = 10;
var myFunction = function() {
    clearInterval(interval); // Stop the current interval
    counter *= 10; // Increment the counter
    interval = setInterval(myFunction, counter); // Set a new interval with the updated counter
}
var interval = setInterval(myFunction, counter); // Start the initial interval

This anonymous function clears the current interval, adjusts the counter value, and then sets a new interval with the updated counter.

Alternative Solution: Using setTimeout

As an alternative to using clearInterval and setInterval, you could leverage setTimeout to implement the interval adjustment. This approach eliminates the need to clear the previous interval:

var counter = 10;
var myFunction = function() {
    counter *= 10; // Increment the counter
    setTimeout(myFunction, counter); // Set a new timeout with the updated counter
}
setTimeout(myFunction, counter); // Start the initial timeout
