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:
- Single line comment
- multi line comment
