"Hello World!" It's a tradition to start with the classic "Hello World!" program. In Ruby, you can print it to the console using the puts command:

puts "Hello World!"

Basic Operations: Experiment with basic arithmetic operations, variable assignments, and data types in IRB:

puts 10 + 5  # Outputs 15
puts 20 - 10 # Outputs 10
puts 3 * 4   # Outputs 12

# Variable assignment
name = "Alice"
puts "Hello, #{name}!" # Outputs "Hello, Alice!"

Explore Resources: There are countless online resources available for learning Ruby, from interactive tutorials to detailed documentation. Explore these resources, join online communities, and ask for help when you need it.
