Fight!
Popularity
Moment has a long history and has been a popular choice for date and time manipulation in JavaScript. It has a large community and is widely used in many projects. Day.js, on the other hand, is a relatively newer library but has gained popularity due to its smaller size and modern API.
Size
Day.js is significantly smaller in size compared to Moment. Day.js is focused on providing a minimal and lightweight alternative to Moment. It achieves this by following a modular design and allowing you to import only the specific functionalities you need. Moment, on the other hand, has a larger bundle size due to its more extensive feature set.
Functionality
Both Moment and Day.js offer a wide range of date and time manipulation functionalities. Moment has been around for longer and has a more comprehensive feature set. It provides additional features like parsing and formatting localized dates, duration calculations, and relative time. Day.js aims to provide a similar feature set to Moment but with a smaller footprint, focusing on the most commonly used functionalities while omitting some of the less frequently used features.
API Design
Moment follows a more traditional, mutable, and object-oriented API design. It provides a fluent and chainable API that allows for complex date manipulations. Day.js, on the other hand, follows a more modern and functional API design inspired by libraries like Moment. It offers a chainable API for method calls but is more focused on immutability and follows a 'zero side-effect' principle.
Compatibility
Moment is compatible with a wide range of JavaScript environments, including browsers and server-side frameworks. Day.js also offers good compatibility and can be used in both browser and server-side environments. Additionally, Day.js provides plugins for integration with popular frameworks like React and Vue.js.
Maintenance
Moment has been a stable and well-maintained library for a long time. However, its development and updates have slowed down compared to Day.js, as Moment has announced that they will no longer be adding new features and are recommending users to migrate to other libraries. Day.js, being a newer library, is actively maintained and has a more responsive development team.
