funkia / jabz Goto Github PK

Hi, Is there currently, or plans for, something like Data.Validation? Aim, to be able to perform multiple validation checks and get a list of errors for an input field? Thanks.

Why no either monad support?

Just wanted to mention, there is another library with its own go-notation:

I'd say a chief obstacle for new developers in learning algebraic type classes is the terminology. To people who are already comfortable with it, they probably find this concern trifling. But I think it's more significant than they think, and I think that friendlier type class names would make a big difference towards accessibility.

Simon Peyton-Jones himself has said he dislikes the choice of the name "Monad" and prefers "Workflow", which they use in F#. Similar renaming could be thought of for Functor, Semigroup, etc. A reference page could be kept to map these custom names to the Haskell/Category theory names.

Would be curious to hear your thoughts on this

The following code

findLast(a => a < 3, [1,2,3,4]);

makes typescript throw this error:
Property 'foldr' is missing in type 'number[]'.
