@nod/swiss-kase 🇨🇭 🧀 🔪

(WIP)

Switch Case as good as Swiss Cheese. Idiomatic-like, dynamic, functional, predictable, stateless, mature, low-fat and fun 🎈 at the same time.

Käse,|kɛːzə|: Cheese (🇩🇪,🇨🇭)

Usage

swiss (needle: any, defaultNeedle?: any = undefined) -> (...haystack: kase())

kase (haystack: any) -> returnValue: any) -> (needle: any)

Simple

import { swiss, kase } from '@nod/swiss-kase'

swiss('Raclette')(kase('Brie')('Nope'), kase('Raclette')('Yes')) // -> 'Yes'

Fun 🧀 🔪

import swissKase from '@nod/swiss-kase'

swissKase['🧀'](1)(
  swissKase['🔪'](1)('Fondue')
  swissKase['🔪'](2)('Feta')
  swissKase['🔪'](3)('Gorgonzola')
) // -> 'Fondue'

With Default Value

swiss('Irrelevant Value')(
  kase('Italian')(['Parmeggiano', 'Ricotta']),
  kase('French')(['Roquefort']),
  kase()(['Appenzeller', 'Emmentaler', 'Sbrinz', 'Raclette'])
) // -> ['Appenzeller','Emmentaler', 'Sbrinz', 'Raclette']

With Multiple Matches

swiss('WOULDNT MATCH', 'Swiss')(
  kase('Parmeggiano', 'Ricotta')('Italian'),
  kase('Roquefort')('French'),
  kase('Gruyère', 'Emmentaler', 'Sbrinz', 'Raclette')('Swiss')
) // -> 'Swiss'

With Custom Defined Default Value

swiss('Irrelevant Value', 'Swiss')(
  kase('Italian')(['Parmeggiano', 'Ricotta']),
  kase('French')(['Roquefort']),
  kase('Swiss')(['Gruyère', 'Emmentaler', 'Sbrinz', 'Raclette'])
) // -> ['Gruyère','Emmentaler', 'Sbrinz', 'Raclette']
