String Interpolation

Interpolation places variable values and expressions inside a string.

string_interpolation.rb

name = 
points = 7

message = "#{name} scored #{points * 2}"
tag = "#{name.downcase}-#{points}"

puts message
puts "tag=#{tag}"

name = 
points = 7

message = "#{name} scored #{points * 2}"
tag = "#{name.downcase}-#{points}"

puts message
puts "tag=#{tag}"

name = 
points = 7

message = "#{name} scored #{points * 2}"
tag = "#{name.downcase}-#{points}"

puts message
puts "tag=#{tag}"

interpolation Ruby evaluates `#{...}` inside a double-quoted string.
