Can you explain why sometimes you use params[:title] vs params["title]?

Treehouse TeacherLai Yi Ohlsen In Sinatra, it doesn't matter whether you use a symbol or a string to access the params object. params converts any symbol you pass as a key to a string before it looks up the corresponding value.
Don't try this with an ordinary Ruby Hash, though! In that case, :foo and "foo" will be two different keys, with two different values!
my_hash = {:foo => 1, "foo" => 2}
puts my_hash[:foo]
puts my_hash["foo"]
Output:
1
