Comments
Many of the source code examples that come with this book are documented with comments that are ignored by the Ruby interpreter. You can place a comment after the hash mark (#
). The text on a line following this character is all treated as a comment:
# this is a comment puts( "hello" ) # this is also a comment
If you want to comment out multiple lines of text, you can place =begin
at the start and =end
at the end (both =begin
and =end
must be flush with the left margin):
=begin This is a multiline comment =end
