Challenge 3: An Array of Hashes — Solution

people = [
  { name: "Philip", age: 33 },
  { name: "Alex", age: 28 },
  { name: "Jordan", age: 41 }
]

people.each do |person|
  puts "#{person[:name]} is #{person[:age]} years old."
end

=begin
Output:
Philip is 33 years old.
Alex is 28 years old.
Jordan is 41 years old.

Notes:
- people is an Array containing three Hash objects, each using symbol keys
  (:name, :age) per the chapter's shorthand syntax.
- .each do |person| ... end loops over the array, binding each hash to the
  block variable person in turn — this is the standard Ruby iteration
  pattern, previewed here ahead of the full Control Flow chapter.
- person[:name] and person[:age] read values out of each hash using symbol
  keys, and string interpolation (#{ }) builds the sentence directly from
  those values with no manual type conversion needed.
