柯里化函数

function curry(fn) {
    var slice = [].slice;
    var len = fn.length;

    return function curried() {
        var args = slice.call(arguments);
        if (args.length >= len) {
            return fn.apply(null, args);
        }

        return function () {
            return curried.apply(null, args.concat(slice.call(arguments)));
        };
    };
}

var add = curry(function (a, b, c, d) {
    return a + b + c + d;
});

console.log(add(1)(2)(3)(4)); // 10
console.log(add(1, 2, 3)(4)); // 10
console.log(add(1)(2, 3)(4)); // 10

add(2)(5); // 7 & 柯里化 curry

js 实现, 函数 add(1)(2)(3); 无限极累加
