Computer science: a bit about regex anchors

Self-tutoring about regular expressions: the tutor mentions a possible misstep.

It’s true that, typically, in regex, ^ means beginning and $ means end – particularly outside of [].

Consider the string s1: “Hello there Smedley!”

The pattern ^there$ won’t find a match in s1, at least not in my experience. However, ^Hello will; also, ley!$ will.
