Moment.js is a javascript date library that helps create, manipulate, and format dates without extending the `Date` prototype.
The moment npm package is a JavaScript library for parsing, validating, manipulating, and formatting dates. It is widely used for handling dates and times in Node.js and browser applications.
Parsing
Parse a date string into a moment object.
moment('2023-04-05')Validation
Check if a date is valid.
moment('2023-04-05').isValid()Manipulation
Manipulate dates by adding time to the current date.
moment().add(7, 'days')Formatting
Format a moment date object into a string in a specified format.
moment().format('YYYY-MM-DD')Query
Query dates to compare them.
moment().isBefore('2023-12-25')Provides a collection of simple, pure functions for manipulating JavaScript dates. It is modular, allowing you to pick and choose which functions you need, and is generally considered to be a lighter-weight alternative to moment.
Created by one of the original Moment.js team members, Luxon is a modern library for working with dates and times. It offers a fluent API and aims to have a smaller footprint than moment.
Day.js is a minimalist JavaScript library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API. It is lightweight and its API is designed to be familiar to Moment.js users.
