method
puts
puts(*args)
public
Writes the given object(s) to ios. Writes a newline after any that do not already end with a newline sequence. Returns nil.
The stream must be opened for writing. If called with an array argument, writes each element on a new line. Each given object that isn’t a string or array will be converted by calling its to_s method. If called without arguments, outputs a single newline.
$stdout.puts("this", "is", ["a", "test"])
produces:
this is a test
Note that puts always uses newlines and is not affected by the output record separator ($\).
