Package Exports

@7urtle/lambda

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@7urtle/lambda) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Why @7urtle/lambda

Lambda was created to allows us to embrace functional programming in JavaScript. It focuses on providing highly performant code which is itself built using functional paradigms. Provided functions are simple, curried, pure and optimised for partial application and function composition.

Focus on your own skill level

@7urtle/lambda was written to help you transition towards functional programming no matter your skill level. You can pick up any functional features as you learn at your own pace. At the end you can master everything including pure functions, composition, currying, functors, and monads.
