Ruby: Newline and Indentation

What does newline mean in Ruby?

• Newline or semicolon is used to separate expressions. p(3); is the same as p(3) on a line by itself.

What does indentation mean in Ruby?

• Indentation (tabs or spaces) has no meaning.

Function Argument's Parentheses May be Omitted

• Parentheses for function/method's arguments are often optional. e.g. p(3) is the same as p 3.

(Tip: this is similar to Perl)
