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            }        }    }}
