bruh

i wish im smart

old thread, but I'd recommend hiding the actual regex in a variable that suggests it's regex so nobody ever has to guess what it is. If you know it's a "regular expression", then yes it's readable.

I came up with the same answer but the test didn't like what I wrote. So I came to the solutions because I was going crazy lol.

absoultely, 100% - very readable imho

would you use this as production code? is it readable enough?

Would adding a multiline operator to the regex be useless?

According to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date
Parsing of strings with Date.parse is strongly discouraged due to browser differences and inconsistencies.
It's better to use constructor Date("date") IMHO.
How can I take my voice back for Best Practice?

so regex aren't case sensitive?

Great solution!
