How To Block Comment In Ruby

Block comments come in handy when you need to write longer explanations or instructions within your code. It is often used when you want to temporarily disable a section of your code without removing it. In this blog post, we will look at how to create block comments in Ruby.

Using the =begin and =end Syntax

In Ruby, you can create a block comment by using the =begin and =end syntax. These special markers indicate the start and end of a block comment, respectively. Anything between these markers will be treated as a comment and ignored by the Ruby interpreter.

=begin
  This is a block comment.
  You can write multiple lines of text here.
  The Ruby interpreter will ignore everything between =begin and =end.
=end
puts "Hello, World!"


        Note that =begin and =end must be at the beginning of a line and should not be indented. Additionally, there should be no whitespace or other characters between the equal sign (=) and the keywords “begin” and “end.”
    
Using Inline Comments

        If you only need to comment out a few lines of code, you can use the inline comment syntax by inserting the hash symbol (#) at the beginning of each line you want to comment out. This is a quicker way to create block comments in Ruby, especially for smaller sections of code.
    
# This is an inline comment
# You can also create block comments by using
# inline comments for each line
puts "Hello, World!"


        While inline comments are easier to write, they might not look as neat as using the =begin and =end syntax for longer sections of code.
    
Conclusion

        In this blog post, we have learned how to create block comments in Ruby using the =begin and =end syntax, as well as using inline comments. Remember to keep your comments concise and informative to help other developers understand your code better.
