Scala.js

Scala.js is a tool that allows developers to write code in Scala—a modern programming language known for expressiveness and safety—and then convert that code into JavaScript, which runs in web browsers. This enables creating complex, reliable web applications using Scala’s features while ensuring compatibility with websites and browser environments. Essentially, Scala.js bridges the gap between the powerful Scala language and the widespread use of JavaScript on the internet, making it easier to build maintainable and scalable web software with the benefits of both worlds.
