    JavaScript provides mechanisms to execute code at specific intervals or after a delay, commonly referred to as timing events. These are primarily handled using the setTimeout and setInterval methods, which are part of the window object.

    Delayed Execution with setTimeout

    The setTimeout method executes a function after a specified delay in milliseconds. It is useful for scheduling one-time tasks.

    Example:

    // Execute a function after 3 seconds
    setTimeout(() => {
    console.log("Hello, world!");
    }, 3000);
    Copied!

    To cancel a scheduled setTimeout, use clearTimeout with the identifier returned by setTimeout:

    let timer = setTimeout(() => {
    console.log("This will not run.");
    }, 3000);

    // Cancel the timeout
    clearTimeout(timer);
    Copied!

    Repeated Execution with setInterval

    The setInterval method repeatedly executes a function at specified intervals in milliseconds. It is ideal for tasks like updating a clock or polling data.
