What is global match in regex?
g is the global search flag. The global search flag makes the RegExp search for a pattern throughout the string, creating an array of all occurrences it can find matching the given pattern. So the difference between /. +/g and /. +/ is that the g version will find every occurrence instead of just the first.
What is Z in regex?
If you only want a match at the absolute very end of the string, use \z (lower case z instead of upper case Z). \A[a-z]+\z does not match joe\n. \z matches after the line break, which is not matched by the character class.
