Why does code not work without "response.end('some string')?"

I wrote the code exactly as it appeared in this exercise yet on every test I do, the browser hangs for about 30 seconds and eventually just times out. I checked the network tab and it says the request failed.

To get my code to work, I have to add 'response.end("something");' to all of my callback functions.

Why is it that Chalkers' code loads nearly immediately with no hang, and mine does not?

response.end() is always needed to let the server know we're done building the response send, anything left and close browser connection. It doesn't need an argument but is it needed to wrap thing up. You'll see that Andrew goes back near the end of the video and adds response.end()'s after the view calls.

The explanation on nodejs.org is : response.end([data][, encoding][, callback]) "If data is specified, it is equivalent to calling response.write(data, encoding) followed by response.end(callback)". All the argument in the end function are optional.

As you have written response.end("footer \n"); response.end("end")//delete if necessary ----- " ; " missing at end of function response.end("end!"); //delete if needed

Hope this help
