print "Milan"
Milan => nil

puts "Milan"
Milan
=> nil

p "Milan"
"Milan"
=> "Milan"

3.times { print "Hello!" }
Hello!Hello!Hello!=> 3

3.times { puts "Hello!" }
Hello!
Hello!
Hello!

puts vs. print vs. p

The puts (short for "put string") and print commands are both used to display the results of evaluating Ruby code.

Both puts and print call the to_s method on the object AND return nil.

The primary difference between them is that puts adds a newline after executing, and print does not

They don`t RETURN anything so the RETURN value is nil.

Using p calls the inspect method on the object.

print "Milan"
# Milan => nil

puts "Milan"
# Milan
# => nil


p "Milan"
# "Milan"
# => "Milan"

3.times { print "Hello!" }
# Hello!Hello!Hello!=> 3

3.times { puts "Hello!" }
# Hello!
# Hello!
# Hello!
# => 3

3.times { p "Hello!" }
# "Hello!"
# "Hello!"
# "Hello!"
# => 3
