error: Do not use Array index in keys

Question

I am using index to generate key in a list. However, es-lint generates an error for the same. React doc also states that using the item index as a key should be used as last

Answer 1

use the following lib "react-uuid" : https://www.npmjs.com/package/react-uuid.

react-uuid basically create random ids when you call it each time.

import React from 'react'
import uuid from 'react-uuid'

const array = ['one', 'two', 'three']

export const LineItem = item => 
{item}

export const List = () => array.map(item => )

and this should solve the issue.
