How to Fix: Update React component every second

Update React component every second using setTimeout and setState

Quick Answer: {"code": "import React, { Component } from 'react'; class TimeComponent extends Component { constructor(props){ super(props); this.state = { time: Date.now() }; } componentDidMount() { console.log("TimeComponent Mounted..."); setInterval(() => { this.setState({ time: Date.now() }); }, 1000); } } export default TimeComponent;

To update the React component every second, you can utilize JavaScript's built-in setInterval function in conjunction with the React lifecycle method componentDidUpdate. This will periodically trigger a re-render of your component.

Method 2: Using setInterval and componentDidUpdate

class TimeComponent extends Component {
constructor(props) {
