在高频场景下 dayjs.diff 会成为性能瓶颈, 发现在进行 dayjs.diff(time, 'day') 计算时会有无效的一些计算,于是优化了在进行 diff day 场景下的性能

test case

const dayjs =  require('./dayjs.min.js');

let startTime = Date.now();
let endTime = Date.now() + 30 * 24 * 60 * 60 * 1000;

for(let i = 0; i < 100000; ++i) {
    dayjs(startTime).diff(endTime, 'day');
}
