poly-apply

Polymorhic curried functional applicator

Motivation

Removing the difference between Promises and syncronous function arguments greatly simplifies tool-building

Features

• Seamlessly applies functions to promises and synchronous values
• Supports functions of one or many arguments
• Recognises cnostants

Installation

npm install poly-apply

Usage

import apply from 'poly-apply'


const wow = (x, y) => `wow ${x} ${y}!`

// Simple usage
console.log(apply(wow, ['such', 'doge']))
// -> wow such doge!

apply(wow, ['much', Promise.resolve('approve')]).then(console.log)
// -> wow much approve!

apply(wow, Promise.resolve(['very', 'such'])).then(console.log)
// -> wow very such!

// Higher-order function style
const wowApplicator = apply(wow)

console.log(wowApplicator(['such', 'doge']))
// -> wow such doge!

// Constant
const constant = apply('Much Wow!')
console.log(constant(['such', 'doge']))
// -> 'Much Wow!'
