Ruby: Print

By Xah Lee. Date: 2022-12-25.

To print, use p, puts, print.

# ruby
a = 5
b = "rabbit"
p a, b, 3 # prints each on a new line.

parenthesis optional

p a, b, 3

can be written as

p(a, b, 3)

parenthesis are often not necessary

puts prints in a human readable form, and adds newline after each argument. For example, string is printed without quotes, array are printed without the brackets or separators.
p prints in a technical form. e.g. string include the quotes. This is good for debugging.
print is similar to “puts” but does not add newline.
