curry

Fast curry implementation with placeholders and function-bind-syntax support.

Installation

npm install @riim/curry --save

Usage

Basic

var curry = require('@riim/curry');

var sum = curry(function(a, b) { return a + b; });
var addOne = sum(1); // or sum(curry.__, 1)

console.log(addOne(2));
// => 3

Placeholders

var curry = require('@riim/curry');

var setProperty = curry(function(obj, name, value) {
	obj[name] = value;
	return obj;
});

var setUserAge = setProperty(curry.__, 'age');

console.log(setUserAge({}, 30));
// => { age: 30 }

ES.Next syntax

import { curry, __ } from '@riim/curry';

let setProperty = curry((obj, name, value) => {
	obj[name] = value;
	return obj;
});

let setUserAge = setProperty(__, 'age');

console.log(setUserAge({}, 30));
// => { age: 30 }

Function bind syntax

import { curry, __ } from '@riim/curry';

let setProperty = ((obj, name, value) => {
	obj[name] = value;
	return obj;
})::curry();

let setUserAge = setProperty(__, 'age');

console.log(setUserAge({}, 30));
// => { age: 30 }

Benchmark

Create - sum = curry((a, b) => a + b) - least important result
Lift - addOne = sum(1)
Call - addOne(2) - much more important result than the previous two

Results in K ops/sec.
