javascript - Use moment.js to generate the data structure of the calendar for the specified month

Please give me a best practice. I’m not familiar with moment (I’ve been looking at the API for a day and I understand the basics). I don’t want to take the wrong path, so I can just give you the final data structure, such as [[26,27,28,1,2 ,3,4], [], [], ...] Thanks, ugh haha
