Here it is in action!

function addThreeNums(a, b, c) { return a + b + c; } var addOneTwo = curry(addThreeNums, [1, 2]); console.log(addOneTwo(3)); // 6

Yeah, like this. You don't need the first slice.

function curry(fn, presets) { return function() { return fn.apply(null, presets.concat([].slice.call(arguments, 0))); }; }

function curry(fn, presets, binding) { return function() { return fn.apply(binding, presets.concat([].slice.call(arguments, 0))); }; }
