注释是Ruby代码中的注释行，在运行时会被忽略。一行注释以＃字符开头，它们从＃延伸到该行的末尾，如下所示-
#!/usr/bin/ruby -w
# This is a single line comment.
puts "Hello, Ruby!"
执行后，上述程序会产生以下结果-
Hello, Ruby!
您可以使用= begin和= end语法注释多行，如下所示：
#!/usr/bin/ruby -w
puts "Hello, Ruby!"
=begin
This is a multiline comment and con spwan as many lines as you
like. But =begin and =end should come in the first line only.
=end
执行后，上述程序会产生以下结果-
Hello, Ruby!
确保结尾注释与代码之间的距离足够远，并且易于区分。如果一个块中存在多个尾随注释，请对齐它们。例如-
@counter # keeps track times page has been hit
@siteCounter # keeps track of times all pages have been hit
