JScala. Write your JavaScript in Scala

JScala allows writing JavaScript code in Scala by using Scala macros to transform Scala code into valid JavaScript syntax and structure, providing type safety and preventing boilerplate code while writing in a single language. It supports common JavaScript features like variables, functions, classes, and libraries through the Scala syntax and type system.
