MpxUsewatchAtMost
watch有触发次数。
用法
类似于watch，带有一个额外的选项count，用于设置触发回调函数的次数。达到计数后，watch将自动停止。
ts
import { watchAtMost } from '@mpxjs/mpxuse-core'
watchAtMost(
source,
() => { console.log('trigger!') }, // triggered it at most 3 times
{
count: 3, // the number of times triggered
},
)
import { watchAtMost } from '@mpxjs/mpxuse-core'
watchAtMost(
source,
() => { console.log('trigger!') }, // triggered it at most 3 times
{
count: 3, // the number of times triggered
},
)
