JavaScript 自定义函数：compose

<script type="text/javascript">     function compose() {        var funcs = [];        var k = 0;        for (var i = arguments.length - 1; i >= 0; i--) {            funcs[k++] = arguments[i];        }        return function(a) {            var result = a;            for (var i = 0; i < funcs.length - 1;i++) {                result = funcs[i](result);                          }            return result;        }    }    function addOne (a) { return a + 1 }    function multiTwo (a) { return a * 2 }    function divThree (a) { return a / 3 }    function toString (a) { return a + '' }    function split (a) { return a.split('') }    split(toString(addOne(multiTwo(divThree(666))))) // => ["4", "4", "5"]    var testForCompose = compose(split, toString, addOne, multiTwo, divThree);    console.log(testForCompose(666));</script>
