puts(...)
public
Writes the given objects to ios as with IO#print. Writes a record separator
(typically a newline) after any that do not already end with a newline
sequence. If called with an array argument, writes each element on a new line. If called without arguments,
outputs a single record separator.
$stdout.puts("this", "is", "a", "test")
produces:
this
is
a
test
