Modernizr vs Highland.js: 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 Highland.js? The high-level streams library for Node.js and the browser. It manages synchronous and asynchronous code easily, using nothing more than standard JavaScript and Node-like Streams. You may be familiar with Promises, EventEmitters and callbacks, but moving between them is far from seamless.

Modernizr belongs to "JavaScript Compilers" category of the tech stack, while Highland.js can be primarily classified 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, Highland.js provides the following key features:

• Intended to work with node.js(or browserify) environment which is really nice
• No alien concepts(from JavaScript/Node perspective)
• Back-pressure

Modernizr and Highland.js are both open source tools. It seems that Modernizr with 23.9K GitHub stars and 3.04K forks on GitHub has more adoption than Highland.js with 3.21K GitHub stars and 158 GitHub forks.
