Comments ​

Comments are useful for understanding code, making comments and explanations, taking notes, and sometimes writing little jokes.

In general, two types of comment lines appear in programming languages: line comment and range comment. Some programming languages only support one. Jule supports both of these common approaches.

Line Comments ​

Line comments are declared with // and all content from the starting position to the end of the line is considered a comment.

For example:

const Life = 42 // Magic number of life.

Range Comments ​

Range comments are used to comment a certain range. /* is used to start a range comment and */ is used to end it.

Where range comments are exist, they are ignored even if a line comment is written with //. This means your compiler will not ignore the behavior of a range comment closing */ after // characters.

For example:

fn Life(): int { ret 42 /* Magic number of life. */ }
