按日期对desc排序，如果并列，则在javascript数组中按风险排序

我有一组对象，我想按日期首先排序，即desc中的'create_date_format'＆如果平局然后按字母顺序对风险排序，即asc

我尝试过lodash.orderBy（risk_list，['create_date_format'，'risk']，['desc']）但由于日期是字符串格式，因此它按日期字符串中的数字排序，例如，2020年1月28日显示为2020年8月1日之前28高于01。

let arr = [{avoided: 0,
avoided_note: null,
create_date_format: "28 Sep 2020",
id: 209,
notes: "Nothing is happening",
risk: "very high risk",
severity: 3,
severity_name: "High",
type: 1,
type_name: "Internal"}, { avoided: 0,
avoided_note: null,
create_date_format: "23 Sep 2020",
id: 206,
notes: null,
risk: "Risk 12",
severity: 3,
severity_name: "High",
type: 2,
type_name: "External"}, {avoided: 0,
avoided_note: null,
create_date_format: "22 Sep 2020",
id: 202,
notes: "test note",
risk: "test risk",
severity: 3,
severity_name: "High",
type: 2,
type_name: "External"}, { avoided: 0,
avoided_note: null,
create_date_format: "23 Sep 2020",
id: 206,
notes: null,
risk: "abc Risk 12",
severity: 3,
severity_name: "High",
type: 2,
type_name: "External"}]

我想首先在日期上排序，即在desc中创建“ create_date_format”，然后在asc中按字母顺序在“风险”中按字母顺序排序
