如何减少最后一个if判断？代码检查工具只能最多三层for/if嵌套

Question

for (var key in flowConfig) {
   if (flowConfig.hasOwnProperty(key)) {
       var flow = flowConfig[key], //register:{name:'register',flow}
           flowItems = flow.flow;
       for (var i = 0, length = flowItems.length; i < length; i++) {
           var item = flowItems[i];
           if (typeof item.path === 'object') {
              //do something
           } else {
              //do something
           }
       }
   }
}
