Reactive Array.find.

Demo

Usage

import { useArrayFind } from '@reause/shared'

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

Use with reactive array

import { useArrayFind } from '@reause/shared'
import { useState } from 'react'

const [list, setList] = useState([-1, -2])
const positive = useArrayFind(list, val => val > 0) // undefined

setList([...list, 1])
// positive: 1 on the next render

list is a plain read-only array: pass the array directly (e.g. from useState), or ref.current if you keep it in a ref. The result recomputes on the render that passes a new array.

Type Declarations

export type UseArrayFindReturn<T = any> = T | undefined

export function useArrayFind<T>(list: readonly T[], fn: (element: T, index: number, array: readonly T[]) => boolean): UseArrayFindReturn<T>
