How to Build a Chess Clock with JavaScript and setInterval

Chess games can sometimes go on for quite some time. I once heard a story of a chess game between two famous chess grandmasters that went on for over eight hours, with the crowd waiting for them to make a move.

After a while one player said to the other “Aren’t you going to move?” His opponent responded, “I thought it was your turn.”


Chess clocks are used to limit a chess game to a certain amount of time. A chess clock can add a great deal of excitement to a chess game. Many people use these clocks in tournaments and just for fun.

With a chess clock, the goal is to checkmate your opponent before your timer runs out. The first person that runs out of time without checkmating their opponent loses the game.

I will show you how to create a basic chess clock using JavaScript and the setInterval method. setInterval allows you to execute a timed event repeatedly by specifying a time in milliseconds. setInterval can be set to an ID and stopped by calling clearInterval on the setInterval ID.

Here is a simple example of how setInterval works:

let count = 1;

// Assign a timed event to variable timerId.

const timerId = setInterval(() => {

    console.log(`Executing function for ${count} seconds.`);

    // Increment the count variable by one.

    if (count === 11) {

        // Stop event by calling clearInterval on timerId.
        console.log(`Timing event cleared.`);


}, 1000); // Execute event every second (1000 milliseconds = 1 second).

SetInterval example


Here is the blueprint for how the application will look on desktop and mobile.


The programming requirements for this project are:

  • We need two clocks that countdown to zero.
  • We need a start button and a reset button.
  • And we need a way to toggle between the clocks as the time is counting down.
