React Js Convert Timestamp to time age
React Js Convert Timestamp to time age:In React.js, converting a timestamp to a time age involves calculating the time difference between the current time and the provided timestamp, typically in milliseconds. This difference is then transformed into a human-readable format, like "X minutes ago" or "X hours ago," using mathematical operations and conditional rendering. React's state management can be employed to update this age dynamically as time passes, ensuring an intuitive presentation of the elapsed time since the given timestamp

How can you convert a timestamp to a human-readable time ago format in a Reactjs ?
This React.js code converts a timestamp into a human-readable time ago format. It defines a TimeAgo component that takes a timestamp as a prop, calculates the time elapsed since that timestamp, and updates it every second. The calculateTimeAgo function computes the time difference in seconds, and based on that, it formats the output as "X seconds/minutes/hours/days ago" accordingly. The example in the App component displays the result by passing a specific timestamp. This code uses React's useState and useEffect hooks to manage state and perform continuous updates, ensuring the displayed time ago value is always current.

xxxxxxxxxx<script type="text/babel"> const { useState, useEffect } = React; function TimeAgo({ timestamp }) { const [timeAgo, setTimeAgo] = useState(calculateTimeAgo(timestamp)); useEffect(() => { const interval = setInterval(() => { const timeAgoString = calculateTimeAgo(timestamp); setTimeAgo(timeAgoString); }, 1000); // Update every second return () => clearInterval(interval); }, [timestamp]); function calculateTimeAgo(timestamp) { const now = new Date(); const secondsElapsed = Math.floor((now - timestamp) / 1000); if (secondsElapsed < 60) { return `${secondsElapsed} seconds ago`; } else if (secondsElapsed < 3600) { const minutes = Math.floor(secondsElapsed / 60); return `${minutes} minute${minutes !== 1 ? 's' : ''} ago`; } else if (secondsElapsed < 86400) { const hours = Math.floor(secondsElapsed / 3600); return `${hours} hour${hours !== 1 ? 's' : ''} ago`; } else { const days = Math.floor(secondsElapsed / 86400); return `${days} day${days !== 1 ? 's' : ''} ago`; } } return <span>{timeAgo}</span>; } function App() { const timestamp = new Date('2023-08-22 13:00:00'); // Replace with your timestamp return ( <div className="container"> <h3>React Js Convert Timestamp to time age Example</h3> <p>Posted <TimeAgo timestamp={timestamp} /></p> </div> ); } ReactDOM.render(<App />, document.getElementById('app')); </script>Output of React Js Convert Timestamp to time age
