How to useMoment.js Library in Javascript

Moment.js is a popular library for parsing, validating, manipulating, and formatting dates and times in JavaScript. We can leverage its functionality to easily convert a string to 24-hour time format.

First, you need to include the Moment.js library in your project. You can do this by either downloading the library and adding it to your project or using a package manager like npm to install it. Once Moment.js is included in your project, you can use its parsing and formatting capabilities to convert the input string to 24-hour time format.

Example:

JavaScript

// Assuming Moment.js is included in the project
const moment = require('moment');

function convertTo24HourFormat(timeString) {
    // Parse input string using Moment.js
    const parsedTime = moment(timeString, ['h:mm A', 'hh:mm A']);

    // Format parsed time in 24-hour format
    const formattedTime = parsedTime.format('HH:mm');

    return formattedTime;
}

const inputTime = '4:30 PM';
const formattedTime = convertTo24HourFormat(inputTime);
console.log(formattedTime);

Output

16:30
