如何使用requestAnimationFrame实现一个setInterval定时器？

function customizeSetInterval(callback, interval) {
    let timer = null;
    let startTime = Date.now();
    let loop = () => {
        let endTime = Date.now();
        if (endTime - startTime >= interval) {
            startTime = endTime = Date.now();
            callback(timer);
        }
        timer = window.requestAnimationFrame(loop);
    }
    loop();
    return timer;
}
customizeSetInterval((timer) => {
    console.log(1);
    // cancelAnimationFrame(timer);
}, 1000)
