JFP is an opinionated, type-enforced functional programming library. JFP makes use of the Signet type library, not only relying on the types for its own signatures, but also to provide rich type interactions for the user of JFP.

JFP is intended to be the foundation for a strong functional programming paradigm in Javascript with roots in Scheme, but borrowing type and contract philosophies from other languages like Scala. Many common utility functions are provided out of the box, but their contracts are built around the idea that partial application and currying are fundamental to the construction of correct, reliable software in Javascript.

JFP is not a drop-in replacement for Underscore, Lodash or Ramda. Instead it is built around the idea that Javascript is a dynamic language, but sometimes it needs a little help. Types are strongly enforced only when weak enforcement would either limit the revealing of function intent or if contract violation would introduce broken or buggy behavior.

4.2.1

  • Enhanced type error output
  • Updated type signatures with names for type identifiers

v4.1.0

  • Added dependent type definitions to concat and between
  • Added isTypeOf operator to concatable type definition
  • Added notBetween function

v4.0.0

Important breaking changes:

  • Compose now only composes two functions
  • Large number of predicates added
  • Removed all nil returns on non-array functions

v3.5.0

Added notNil and exists types

v3.4.2

Fixed client-side dependency issues

v3.0.0

System overhaul. Code written with earlier versions of JFP will be incompatible with v3.0.0. Currently, there is no migration path planned due to stronger typing and radical contract modification. Although this may be inconvenient for people currently using older versions of JFP, it will, in the long run, be a benefit to all who use the library.

Many functions were eliminated completely either due to underuse, violation of philosophy or they were simply unnecessary given the updated library behavior.
