dayjs().isValid() how to use

dayjs() 返回当前系统时间
dayjs().isValid(); 肯定为true
那么传入一个参数呢？
dayjs(‘2018-08-107’).isValid();
dayjs(‘2018-13-01’).isValid();
dayjs(‘1-10-01’).isValid();
结果都是true！

是我打开方式不对吧 “…“

Actually，
new Date(2018,13,01) => 2019-01-31T16:00:00.000Z
new Date(‘2018-08-107’) => Invalid Date
new Date(‘1-10-01’) => Invalid Date

But
dayjs(‘2018-13-01’).isValid(); => true
dayjs(‘2018-08-107’).isValid(); => true
dayjs(‘1-10-01’).isValid(); => true

so, there must be something wrong with the isValid function.
isValid() { return !(this.$d.toString() === 'Invalid Date') }

woooh~~~~
the result is different between chrome and firefox.
firefox doesn’t support string like ‘1-10-01’, but new Date(1,10,01) is ok.

format like (yyyy, mm-1, dd, hh, mm, ss) or (mm/dd/yyyy hh:mm:ss) are much more compatible.
