Moment is a JavaScript library for parsing, validating, and manipulating dates and times. It simplifies working with dates by providing an intuitive API for formatting, comparing, and converting dates across different timezones and locales. Developers use Moment when they need to handle complex date operations without relying on the browser's built-in Date object, which has inconsistent behavior across platforms.
