const list = [ref(1), ref(-1), ref(2)]
const positive = useArrayFind(list, val => val > 0)

import { useArrayFind } from '@vueuse/core'

const list = [ref(1), ref(-1), ref(2)]
const positive = useArrayFind(list, val => val > 0)
// positive.value: 1

Use with reactive array

import { useArrayFind } from '@vueuse/core'

const list = reactive([-1, -2])
const positive = useArrayFind(list, val => val > 0)
// positive.value: undefined
list.push(1)
// positive.value: 1
import { useArrayFind } from '@vueuse/core'

const list = reactive([-1, -2])
const positive = useArrayFind(list, val => val > 0)
// positive.value: undefined
list.push(1)
// positive.value: 1
