Good work! Now we’ll want to create the main body of our program: the case statement, which will decide what actions to take based on what the user types in.

if and else are powerful, but we can get bogged down in ifs and elsifs if we have a lot of conditions to check. Thankfully, Ruby provides us with a concise alternative: the case statement. The syntax looks like this:

case language
  when "JS"
    puts "Websites!"
  when "Python"
    puts "Science!"
  when "Ruby"
    puts "Web apps!"
  else
    puts "I don't know!"
end

The else is what the case statement will do if it doesn’t match any of its when statements to the case (in this case, the value of language).
