Lesson 1 of 15
Hello, World!
Your First Ruby Program
Ruby's built-in method for printing output is puts:
puts "Hello, World!"
puts prints the value and adds a newline at the end. You can also use print (no newline) and p (prints the inspect representation):
puts "hello" # hello
print "hi" # hi (no newline)
p 42 # 42
p "text" # "text" (with quotes)
Comments
Single-line comments start with #:
# This is a comment
puts "code" # This is also a comment
Your Task
Print exactly Hello, World! using puts.
