我的代码中出现循环错误

Question

下面是我的代码，我不想使用for循环。但是希望我的价值每次都会增加。但它不应该再次为0，我将其初始化为0.任何建议

            _updateAll: function(store,data) {
                console.log("data values", data);
                that = this;
                //if ( var i < 0)
                var i = ++i || 0;
                //} 
                //a = 1;
                Rally.data.BulkRecordUpdater.updateRecords({
                    records: data,
                    propertiesToUpdate: {
                        Parent: that._newParent.get("_ref")
                    },
                    success: function(readOnlyRecords){
                        //all updates finished, except for given read only records
                    },
                    //updateRecords: function(options) {
                        //console.log("not updated records", options.success.notUpdatedRecords);
                    //},
                    scope: that
                }); 
                console.log("final features value", that.final_features[0]);
                console.log("final features value2", that.final_features);
                that._createNewItems(that.final_features[i], data[i]);
                //i = ++a;
                console.log()
            },
