React vs Scala.js: What are the differences?
React: A JavaScript library for building user interfaces. Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project; Scala.js: *The Scala to JavaScript compiler *. It is a safer way to build robust front-end web applications. With it, typos and type-errors are immediately caught and shown to you in your editor, without even needing to compile your code. Refactor any field or method with ease, with the confidence that if you mess it up the editor will tell you immediately.
React belongs to "Javascript UI Libraries" category of the tech stack, while Scala.js can be primarily classified under "JavaScript Compilers".
React and Scala.js are both open source tools. React with 134K GitHub stars and 24.9K forks on GitHub appears to be more popular than Scala.js with 3.71K GitHub stars and 325 GitHub forks.
