A functional implementation of switch

functionnal-switch.js

// simple example
const isFruitOrVegetable = switch(
  case('apple', 'isFruit'),
  case('orange', 'isFruit'),
  case('eggplant', 'isVegetable'),
  default('isFruit')
);

isFruitOrVegetable('apple') // isFruit


// We can also pass regular expressions or functions to case.
// For example:
case(
  /apple/, 
  () => 'isFruit'
)

case(
  str => str.includes('eggplant'),
  () => 'isVegetable'
)
