We have our own monadic type system which is continuously under development. The aim of this system is to ensure type-safety, reduce complexity of logic and control-flows, improve legibility of code, and improve TypeScripts ability to do type-inference et al.

We currently have the main data types of JS represented

• None (undefined)
• Nil (null)
• Num (Number)
• Str (String)
• Bool (Boolean)
• List (Array)
• Dict (Object || Map)
