b = 3; // 00000000000000000000000000000011

print(a ^ b); // 00000000000000000000000000000110

Answer 2

The ^ is "starts with"
The $ is "ends with"

Example /^c[a-z]+t$/ will match any string that begins with c and ends with t and have character(s) in between. So cat, cut , coat, for instance can all be matched

The dot, when not escaped means "any character"
