A Comment on Comments

Despite your best efforts to maintain good code style, your programs may become difficult to decipher as they grow more complex. A comment is a note ignored by the interpreter. Comments clarify code for human readers (including you!). Many code snippets in subsequent chapters will have comments.

In Ruby, anything following a # is a comment. An enclosing =begin and =end create multiline comments.

# my favorite dessert!
fave_dessert = "pie"

=begin
Guess how many pies I can eat in one sitting.
You ready?
=end

num_pies = 3.14 # :)
