Ruby comments are non executable lines in a program. These lines are ignored by the interpreter hence they don't execute while execution of a program. They are written by a programmer to explain their code so that others who look at the code will understand it in a better way.
Types of Ruby comments:
Ruby Single Line Comment
The Ruby single line comment is used to comment only one line at a time. They are defined with # character.
The Ruby multi line comment is used to comment multiple lines at a time. They are defined with =begin at the starting and =end at the end of the line.
