As you can see even in the blog post: straightforward readable code using built-in functionality is turned into 8-12 imports, a bunch of auxillary functions and multiple function calls that obscure the actual functionality. At 35 times speed penalty and 2 times memory penalty.

JS simply does not lend itself to currying, data-last signatures, piping, and pattern matching like an ML family language does. And as you can tell by the Ramda typings, neither does the TS type system. [0]

You will forever fight an uphill battle against every single tutorial and piece of documentation and colleague when going down this path. I don't think the effort is worth it.
