Ruby is a dynamically typed Language, as we see in the above code, we assigned a number, a string value and a boolean to three different variables

'puts' is a function that takes a list of arguements and prints to console on a new line, You may use print statement as well, the only difference is, it prints in continuation.

printmy_num,my_string,my_bool

my_num, my_string and my_bool are variables which are holding different objects. For naming variables in ruby we use snakecase as a convention.

Everything is a an Object in Ruby,

Everything!

To find out class of a ruby object we can call a 'class' method on any object.

putsmy_num.class(),my_string.class(),my_bool.class()

Fixnum
String
TrueClass
