                    return o.due
                });
            }
        }
 return _.assignIn(_.clone(reactiveTableSettings), {
        showFilter: true,
        showNavigation: 'auto',
        showColumnToggles: false,
        collection: LocalCollection,
        rowsPerPage: 10,
        showRowCount: true,
        fields
    });
};

This part doesn’t return anything really, you’re looping through but not setting a value. Did you mean value.map or something else that would combine the results into a return variable?

I want return one by one with property o.period also. Any suggestions
