params is a hash
@message = params[:message_1]

the syntax for adding key value pairs using params is URL?key=value&key=value&key=value&key=value  <- this would create 4 key value pairs
e.g. http://localhost:3000/api/query_params?my_message=jimm&message_2=i meant jimmy&message_3=that's better

g <--abbreviation for generate in rails
c <--abbreviation for console in rails
s <--abbreviation for server in rails

puts does not go to the browser, it goes to the terminal

nil and null mean the same thing; depends on the language which is used

get '/segment_params/:this_is_a_variable' => 'params_examples#segment_params_action' <--  /:  is a wildcard in URL segments
