is being used to grab data, or in a regex that's just there to verify if something's correct, it is bad most of the time.
BUT... If s///
is used, .*
often is the right
Please don't use [\s\S]*
etc because someone told you .*
is bad. You can use .*
if you know it's right. (btw, .
doesn't match \n
is used, [\d\D]
and friends do match \n
Summary: if you know what it does, and it does what you want, .*
is not bad.
