What's a prefix regular expression?

Tags:

regex

I'm reading something that mentions prefix regular expressions, and sites as an example /^joey/

What's a prefix regular expression? Does that mean it starts with a caret?

in REGEX ^ at the start of a regex means, "Starts with"

/^joey/

Would therefore match any string that starts with "joey" such as "joeyjoey" or "joey and jane"
