requestAnimationFrameTimeStampTest(): Promise<unknown>

返回 Promise<unknown>

已被弃用

检测requestAnimationFrame提供的时间是否准确！如果为false，说明requestAnimationFrame回调函数提供的时间有误！

示例

function requestAnimationFrameTimeStampTest() {
    return new Promise((resolve, reject) => {
        const startTimeStamp = performance.now();
        requestAnimationFrame(timeStamp => resolve(timeStamp > startTimeStamp));
    });
}
requestAnimationFrameTimeStampTest().then(console.log);
