    import { Canister, Duration, ic, TimerId, Tuple, update } from 'azle';

    export default Canister({

            [Duration],

            (interval) => {
                const functionTimerId = ic.setTimerInterval(interval, callback);

                const capturedValue = '🚩';

                const closureTimerId = ic.setTimerInterval(interval, () => {
                    console.log(
                        `closure called and captured value ${capturedValue}`
                    );
                });

                return [functionTimerId, closureTimerId];

    });

    function callback() {
        console.log('callback called');
