Package Exports

curry

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (curry) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

CURRY

A curry function without anything too clever (... because hunger is the finest spice)

install

npm install curry

Usage

//-- creating a curried function is pretty
//-- straight forward:
var add = curry(function(a, b){ return a + b });

//-- it can be called like normal:
add(1, 2) //= 3

//-- or, if you miss off any arguments,
//-- a new funtion that expects all (or some) of
//-- the remaining arguments will be created:
var add1 = add(1);
add1(2) //= 3;

//-- curry knows how many arguments a function should take
//-- by the number of parameters in the parameter list

//-- in this case, a function and two arrays is expected
//-- (fn, a, b).  zipWith will combine two arrays using a function:
var zipWith = curry(function(fn, a, b){
    return a.map(function(val, i){ return fn(val, b[i]) });
});

//-- if there are still more arguments required, a curried function
//-- will always return a new curried function:
var zipAdd = zipWith(add);
var zipAddWith123 = zipAdd([1, 2, 3]);

//-- both functions are usable as you'd expect at any time:
zipAdd([1, 2, 3], [1, 2, 3]); //= [2, 4, 6]
zipAddWith123([5, 6, 7]) //= [6, 8, 10]
