🎯 Use Nested Interpolation for Dynamic Values

Nested interpolation lets you embed method calls or complex expressions directly into strings for clarity and conciseness. This approach avoids manual concatenation and ensures values are evaluated at runtime. It’s especially handy when you need formatted dates, upcased names, or computed values inline.

name = "Alice"
greeting = "Hello, #{name.upcase}! Today is #{Time.now.strftime('%A')}"
puts greeting
# => "Hello, ALICE! Today is Monday"
