var curry = require('curry');

//-- 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]

//-- the number of arguments a function is expected to provide
//-- can be discovered by the .length property
zipWith.length; //= 3
zipAdd.length; //= 2
zipAddWith123.length; //= 1
