Tip

Key values should be stable, such that they should continue to refer to the same object even after operations that make changes to the array. A common mistake is to use the position of an object in the array as its index, which is not stable because many operations on arrays affect the order of objects.

import React, { Component } from "react";

import { ActionButton } from "./ActionButton";

export class List extends Component {

constructor(props) {

super(props);

this.state = {

names: ["Bob", "Alice", "Dora"]

}

}
