fantasy-derivations\n\nThe [fantasy-land][fantasy-land] spec only requires ADTs to define the minimum\nset of methods necessary for its type. Others can be derived. Fantasyland\ngives the code necessary for the derivations, but leaves it up to either the\nimplementer or consumer to put them to use. `fantasy-derivations` allows you to\naccess methods on various ADTs that can support them without worrying whether\nthey are in fact defined.\n\n[fantasy-land]: https://github.com/fantasyland/fantasy-land\n\n## Example\n\n```js\nvar fallback = require('fantasy-derivations')\nvar monad = require('some-monad-library-with-only-chain-defined')\n\nvar my_monad = monad.of(0)\n\nfallback('map', my_monad)(function (n) { return n + 1 })\n// monad.of(1)\n```\n\n## API\n\nThe exported function takes a string (a method name) and an ADT and does its\nbest to return a function for that ADT matching spec.\n","funding_links":[],"categories":["Libraries"],"sub_categories":["[Javascript](https://developer.mozilla.org/en-US/docs/Web/JavaScript)"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frjmk%2Ffantasy-derivations","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frjmk%2Ffantasy-derivations","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frjmk%2Ffantasy-derivations/lists"}
