最平滑的计时器间隔，可在一定时间内将值最多添加到100

function smoothTimer(targetValue, duration) {
    let start = null;
    let currentValue = 0;

    function step(timestamp) {
        if (!start) start = timestamp;
        const progress = timestamp - start;
        const t = Math.min(progress / duration, 1);
        currentValue = Math.min(currentValue + (targetValue - currentValue) * t, targetValue);

        if (progress < duration) {
            window.requestAnimationFrame(step);
        } else {
            currentValue = targetValue;
        }

        console.log(currentValue);
    }

    window.requestAnimationFrame(step);
}

smoothTimer(100, 5000); // 在5秒内将值平滑地增加到100

currentValue = Math.min(currentValue + (targetValue - currentValue) * t, targetValue);

window.requestAnimationFrame(step);
