logical-operators/index.js

A tiny library that abstracts away logical operators with the intention of improving code readability.

const every = (...validation) => (target) => {
  return validation.reduce((prev, next) => prev && next(target), validation[0](target))
}

const some = (...validation) => (target) => {
  return validation.reduce((prev, next) => prev || next(target), validation[0](target))
}

const or = (first, second) => (target) => first(target) || second(target)

const both = (first, second) => (target) => first(target) && second(target)

const greater = (one) => ({
  than: (second) => one > second
})

const less = (one) => ({
  than: (second) => one < second
})

const equal = (first, second) => (target) => first(target) === second(target)

module.exports = { some, both, or, every, greater, less, equal }
