You're comparing a date type to a string. Cast them to the same type, either both string or both date.

I know,but I don't know what kind of type of dataviewjs date field
I did try .getDate() or .getMonth() but return error

I need the example code or API of the date type

Something like this should work: dv.func.date("2022-09-09") === file.cdate. You also have access to Luxon and Moment in case you're more comfortable with those.

BTW, file.date is incorrect. The file object is its own thing. date is directly under page here. As always, I encourage using the console to experiment.
