Fable vs Scala.js: What are the differences?

Fable: F# to JavaScript Compiler. It is a compiler powered by Babel designed to make F# a first-class citizen of the JavaScript ecosystem; 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.

Fable and Scala.js can be categorized as "JavaScript Compilers" tools.

Some of the features offered by Fable are:

• Functional programming and more
• Type safety without the hassle
• Modern Javascript output

On the other hand, Scala.js provides the following key features:

• Strong typing
• optimizes your Scala code into highly efficient JavaScript
• use any JavaScript library right from your Scala.js code

Scala.js is an open source tool with 4.01K GitHub stars and 355 GitHub forks. Here's a link to Scala.js's open source repository on GitHub.
