React Js Calculate Hours Between two Dates | Time Difference Between Two Dates

React Js Calculate Hours Between two Dates:Calculating hours between two dates in ReactJS involves using the built-in JavaScript Date object. First, create Date instances for both dates. Then, compute the time difference in milliseconds by subtracting the earlier date from the later one. Convert this difference to hours by dividing it by 3,600,000 (the number of milliseconds in an hour). Finally, handle any rounding or formatting needed. This process enables you to determine the precise time difference in hours between the two input dates using ReactJS.

How can I calculate the hours between two dates using Reactjs?

This React.js code creates a web application that calculates the time difference between two given dates and times. It utilizes state management with hooks (useState) to capture user input for start and end dates. Upon clicking the "Calculate" button, it validates the inputs, calculates the time difference in milliseconds, and converts it into hours and minutes. The calculated time difference is then displayed. The application alerts the user for invalid inputs or if the end date is before the start date. It uses the datetime-local input type for capturing date and time values. The interface is rendered using ReactDOM into an HTML container with appropriate labels and a button.

  <script type="text/babel">
    const { useState } = React;

    function App() {
      const [dateInputs, setDateInputs] = useState({
        startDate: '',
        endDate: '',
      });

      const [timeDifference, setTimeDifference] = useState({
        hours: 0,
        minutes: 0,
      });

      const calculateTimeDifference = () => {
        const startTime = new Date(dateInputs.startDate).getTime();
        const endTime = new Date(dateInputs.endDate).getTime();

        if (isNaN(startTime) || isNaN(endTime)) {
          alert('Please enter valid start and end dates.');
          return;
        }

        if (startTime >= endTime) {
          alert('End date and time must be after start date and time.');
          return;
        }

        const timeDifference = Math.abs(endTime - startTime);
        const hours = Math.floor(timeDifference / (1000 * 60 * 60));
        const minutes = Math.floor((timeDifference % (1000 * 60 * 60)) / (1000 * 60));

        setTimeDifference({ hours, minutes });
