Hi All, I am novice at Dancer, I am sure my question is very easy for you but I decided to ask because I failed at the beginning of my study.
I started reading following manual : *https://metacpan.org/pod/Dancer2::Manual <https://metacpan.org/pod/Dancer2::Manual>* I installed Dancer2, placked up it and opened web page from localhost. Everything is OK until here. There is following info at manual: *The code block given to the route handler has to return a string which will be used as the content to render to the client.* It is clear for following example *get '/test1/:name' => sub { return "Hi there " . params->{name};};* because it returns a string and when I write *http://localhost:5000/test1/kadir <http://localhost:5000/test1/kadir> *to browser I see *Hi there kadir* which is the string I expect to see But next example is as follow: *get '/test2/:name' => sub { "Hey ".param('name').", welcome here!";};* It does not return anything. Because there is no *return* keyword *.* Despite this I see *Hi there kadir *when I write *http://localhost:5000/test2/kadir <http://localhost:5000/test2/kadir>* But above red background colored sentence says that it must return a value *?* Next example is stranger *:get '/test3/:name' => sub { "Hello there, " . defined param('name') ? param('name') : "whoever you are!";};* Again there is no *return* keyword. When I write *http://localhost:5000/test3/kadir <http://localhost:5000/test3/kadir> *I see only kadir. But at test2 example, I saw all words despite there is no return keyword. So what is rule? *-- * *Kadir BeyazlıComputer Engineer* *GSM : +90 535 821 50 00*
