Comments are lines of annotation within Ruby code that are ignored at runtime. A single line comment starts with # charcter and they extend from # to the end of the line as follows:
#!/usr/bin/ruby -w # This is a single line comment. puts "Hello, Ruby!"
Ruby Multiline Comments
You can comment multiple lines using =begin and =end syntax as follows:
#!/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
Make sure trailing comments are far enough from the code that it is easily distinguished. If more than one trailing comment exists in a block, align them. For example:
@counter # keeps track times page has been hit @siteCounter # keeps track of times all pages have been hit
