About
futils is a small (around 10 Kilobytes when minimized and gzipped) library for generic functional programming in javascript. It is divided into several namespaces which you can see below:
| Package | Namespace | Description |
|---|---|---|
| Trampoline | .trampoline |
Useful to create tail recursive functions in a not tail recursive language. |
| Operation | .operation |
Functions that allow to operate with various data structures in a Point-Free form. |
| Lambda | .lambda |
Contains helpers for working with functions, like curry, flip and compose. |
| ADT | .adt |
Allows easy creation of algebraic single and union data types. |
| Generics | .generics |
Building blocks for new data structures which can derive generic methods. |
| Monoid | .monoid |
A collection of some of the most common monoidal structures like Sum and All. |
| Data | .data |
Pre-made data structures. All of these implement various interface contracts (typeclasses). |
