Syntax and types

name = "Ada"
age = 28
price = 29.99

puts "#{name} is #{age} years old"

No semicolons, no parentheses required for method calls without arguments -- Ruby's syntax leans toward reading like natural English wherever it can.

Try it yourself

Exercise: Declare name and age, then puts them using string interpolation.

Expected output: open-ended — there's no single correct output here, just get your code running without errors.
