CoffeeScript vs Pyright: What are the differences?

Developers describe CoffeeScript as "Unfancy JavaScript". CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. On the other hand, Pyright is detailed as "Static type checker for the Python language by Microsoft". Typically 5x or more faster than mypy and other type checkers that are written in Python. It is meant for large Python source bases. It can run in a “watch” mode and performs fast incremental updates when files are modified.

CoffeeScript and Pyright are primarily classified as "Languages" and "Static Type Checkers" tools respectively.

CoffeeScript and Pyright are both open source tools. CoffeeScript with 15.2K GitHub stars and 1.99K forks on GitHub appears to be more popular than Pyright with 4.21K GitHub stars and 138 GitHub forks.
