Ruby Multi-Line Comment

Ruby Multi-Line Comment

Like all other programming languages, Ruby also supports comment syntax out of the box.

We may use the number sign character # to make a single-line comment in Ruby code.

Multi-Line Comment in Ruby

In Ruby, multi-lines comment syntax starts with the =begin token and ends with the =end token. It’s known as a block comment.

There should be no leading whitespace in these tokens.

=begin
Quisque velit nisi, pretium ut lacinia in, elementum id enim.
Praesent sapien massa, convallis a pellentesque nec, egestas non nisi.
Donec rutrum congue leo eget malesuada.
Curabitur arcu erat, accumsan id imperdiet et, porttitor at sem.
=end

Although Ruby has the =begin/=end syntax for making multi-line comments, most Ruby developers favor single-line syntax, which can span multiple lines and is recommended.
