curry-method

curryMethod.js

A lightweight module that helps you curry any methods and use them in a pipe and function composition.

//Curry element.classList.add()
const addClass = curryMethod(1, 'classList.add')
const removeClass = curryMethod(1)('classList.remove')

const element = document.getElementById('test-id')

//Both would work, just like those curried functions provided by Ramda
addClass('first-class')(element)
removeClass('second-class', element)
//These functions is identical with element.classList.add('first-class')

Why do you want to curry methods?

By currying methods, you can easily create partial functions, make it work in a pipe and reuse your code to a greater extent.
