响应式的 Array.findLast。

用法

import { useArrayFindLast } from '@vueuse/core'

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

与响应式数组一起使用

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

类型声明

/**
 * Reactive `Array.findLast`
 *
 * @see https://vueuse.org.cn/useArrayFindLast
 * @param list - the array was called upon.
 * @param fn - a function to test each element.

 */
export declare function useArrayFindLast<T>(
  list: MaybeRefOrGetter<MaybeRefOrGetter<T>[]>,
  fn: (element: T, index: number, array: MaybeRefOrGetter<T>[]) => boolean,
): ComputedRef<T | undefined>
