Event Delegation optimization guide as Expected in React with Dynamic List Items
I've hit a wall trying to I'm having trouble with event delegation in my React application. I'm trying to implement a click handler that should work for dynamically generated list items. However, the event handler isn't being triggered on the newly added items. I have a component that maintains a list of items in its state, and I update this list by adding new items. Here's a simplified version of my code: ```javascript import React, { useState } from 'react'; const ItemList = () => { const [items, setItems] = useState(['Item 1', 'Item 2']); const handleClick = (item) => { console.log(`Clicked: ${item}`); }; const addItem = () => { setItems([...items, `Item ${items.length + 1}`]); }; return ( <div> <ul> {items.map((item, index) => ( <li key={index} onClick={() => handleClick(item)}>{item}</li> ))} </ul> <button onClick={addItem}>Add Item</button> </div> ); }; export default ItemList; ``` The expectation is that each time I click on any item, it should log the item's name. The initial items work perfectly, but the items added after the initial render do not trigger the click event. I noticed that when I add items, they are rendered correctly, but clicking them doesn't log anything. I tried moving the `handleClick` function outside the component but that didn't change anything. I also checked the console for any potential warnings, but there are none. I suspect it might have something to do with how React handles events or the lifecycle of components, but I need to pinpoint the scenario. Has anyone faced similar behavior or can suggest a solution? The project is a microservice built with Javascript. Could someone point me to the right documentation? What would be the recommended way to handle this? For reference, this is a production REST API. What are your experiences with this?
