const cancellable = (fn, args, t) => {
    // 1. `setTimeout()` is used to delay the execution of `fn` (the function) with provided `args` (the arguments).
    // The function `fn` will be called after `t` milliseconds (the delay time).
    const timeoutId = setTimeout(() => fn(...args), t);

    // 2. The `return` statement gives back a function (the cancel function).
    // This cancel function can be called later to clear the timeout before the function `fn` is executed.
    return () => clearTimeout(timeoutId);
