puts, print, and p
puts, print, and p are three ways to show things on screen: puts adds a new line, print stays on the same line, and p shows the value the way a programmer sees it. They are like three different ways of speaking out loud.

p valueputs, print, and p
puts prints a value followed by a newline, print prints without adding one, and p prints the value's inspected (debug) representation, including quotes around strings.
p is especially useful while debugging since it makes the type of the value clearer than puts. All three accept multiple arguments.
Note:
Use
p instead of puts when debugging, since it shows exactly what type of value you have, quotes and all.Example: puts, print, and p
puts "Hello with puts"
print "Hello with print"
print "\n"
p "Hello with p"
