Need understanding this Ruby Regex code -

-

i attempting become better acquainted ruby regex , came accros in 1 of codewars.com answers.

my current comprehension of regex follows. \w means any non-word character. assuming pipe symbol means effect of between every character , think underscore means all underscores between charecters.

am close? criticism welcomed. thank you.

/\w|_/

in regex: /\w|_/, vertical bar "or". in ruby, _ word character (e.g., abc_def valid word in ruby), , not matched \w. regex above matches non-word character or underscore. can test out @ rubular.com.
