Verdict
dayjs serves as a lightweight alternative to Moment.js, offering a modern API with a focus on immutability and efficiency. It is suitable for projects where bundle size and performance are paramount, especially in frontend applications where every kilobyte matters.
On the other hand, Moment.js provides a comprehensive suite of date manipulation features and is still widely used across various projects. It is well-suited for backend systems or larger applications where its extensive functionalities can be fully leveraged, even if that comes with an increased footprint.
Migrating from Moment.js to dayjs may require some adjustments in code due to API differences, but the reduced bundle size and improved performance can make it worthwhile for new projects or those looking to optimize existing ones.
