const list = [ref(1), ref(-1), ref(2)]
const positive = useArrayFindLast(list, val => val > 0)
// positive.value: 2
與響應式陣列一起使用
js
import { useArrayFindLast } from '@vueuse/core'
const list = reactive([-1, -2])
const positive = useArrayFindLast(list, val => val > 0)
// positive.value: undefined
list.push(10)
// positive.value: 10
list.push(5)
// positive.value: 5
