RapydScript is described as 'Pre-compiler for JavaScript, similar to CoffeeScript, but with cleaner, more readable syntax. The syntax is very similar to Python, but allows JavaScript as well. It's not another Python-in-a-browser clone, it's actually JavaScript with more Pythonic' and is a programming language in the development category. There are more than 10 alternatives to RapydScript for a variety of platforms, including Windows, Linux, Mac, Web-based and BSD apps. The best RapydScript alternative is JavaScript, which is both free and Open Source. Other great apps like RapydScript are TypeScript, CoffeeScript, ReScript and Bosque.

Python-like syntax interpreter implemented with javascript that runs entirely in the web browser and/or in the NodeJS environment.
PureScript was initially designed by Phil Freeman in 2013. He started to work on PureScript since he wasn't satisfied by other attempts to transpile Haskell to JavaScript (e.g. using Fay, Haste, or GHCJS).
Sucrase is an alternative to Babel that allows super-fast development builds. Instead of compiling a large range of JS features to be able to work in Internet Explorer, Sucrase assumes that you're developing with a recent browser or recent Node.
