A collection of tools for functional programming in JavaScript



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). |
| Optic | .optic | van Laarhoven based lenses for Object and Array structures. |
