Recently, i start to learn javascript functional programming. after finishing the curry and compose study, i come across functors, such as Maybe, Either,and IO...etc.However i end up finding that, many functors were written in pure javascript include fantasy-land and ramda-fantasy ,meanwhile, they don't provide any typescript type declaration file.Therefore, the experiences is not good when they are used in typescript. so that i attempt to rewrite it in ts to get a better experience! I am a new hand in FP and write package, it's little hard for me to work.
yarn add fantasy-ts or
npm install fantasy-ts
