The following expressions are not the same: /[.]*/ and /.*/. Why is that, and how exactly are they different? What is the interaction between the [] and special characters in regular expressions?
Thank you.

The dot
.is normally a wildcard, matching any character. Within a character class (the[]) however, it is treated as a literal and only matches a dot.
