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
=end syntax for making multi-line comments, most Ruby developers favor single-line syntax, which can span multiple lines and is recommended.
# This is also # multi-line comments
