How to transform YYYYDDD to DD-MM-YYYY
问题
有没有moment.js或其他库提供的转换器，可以将以YYYYDDD格式给出的日期转换为现代日期，如DD-MM-YYYY或类似的格式？
英文:
I have a date which is given in YYYYDDD format, where YYYY is the year and DDD the days through the year (001-365).
Does the library from moment.js or any other library has a conversor for this kind of given dates to a modern date, like DD-MM-YYYY or something similar?

请看文档中的部分：https://momentjscom.readthedocs.io/en/latest/
// 解析格式为 YYYYDD 的字符串
let momentdate = moment('2023050', "YYYYDDD");
// 转换为格式为 DD-MM-YYYY
let datestring = momentdate.format("DD-MM-YYYY");
console.log(datestring);
