Modernizr vs Luxon: What are the differences?

What is Modernizr? Respond to your user’s browser features. It’s a collection of superfast tests or detects as we like to call them which run as your web page loads, then you can use the results to tailor the experience to the user. It tells you what HTML, CSS and JavaScript features the user’s browser has to offer.

What is Luxon? Library for working with dates and times in Javascript. It is a library that makes it easier to work with dates and times in Javascript. If you want, add and subtract them, format and parse them, ask them hard questions, and so on, it provides a much easier and comprehensive interface than the native types it wraps.

Modernizr can be classified as a tool in the "JavaScript Compilers" category, while Luxon is grouped under "Javascript Utilities & Libraries".

Some of the features offered by Modernizr are:

• Easy to deliver tiered experiences
• Make use of the latest and greatest features in browsers
• Without leaving less fortunate users high and dry.

On the other hand, Luxon provides the following key features:

• DateTime, Duration, and Interval types
• Immutable, chainable, unambiguous API
• Parsing and formatting for common and custom formats

Modernizr and Luxon are both open source tools. It seems that Modernizr with 23.9K GitHub stars and 3.04K forks on GitHub has more adoption than Luxon with 8.61K GitHub stars and 364 GitHub forks.
