nor-function

Function utilities for JavaScript and Node.js

Usage

Install from NPM: npm install -d nor-function

.curry() -- Faster bind() implementation without this

var FUNCTION = require("nor-function");

function sum(a, b) {
	return a + b;
}

var sum_10 = FUNCTION(sum).curry(10);

30 === sum(10, 20);
30 === sum_10(20);

.bind() -- Faster bind() implementation with support for this

var FUNCTION = require("nor-function");

var obj = {
	'base': 100,
	'sum': function(a, b) {
		return this.base + a + b;
	}
};

var sum_10 = FUNCTION(obj.sum).bind(obj, 10);

130 === obj.sum(10, 20);
130 === sum_10(20);

Serialize function to String

var FUNCTION = require("nor-function");
function foo(a, b) { return a + b; }
var str = FUNCTION(foo).stringify();
str === "function foo(a, b) { return a + b; }";

Unserialize string to function

var FUNCTION = require("nor-function");
var str = "function foo(a, b) { return a + b; }";
var fun = FUNCTION.parse(str);
fun(10, 20) === 30;
