function to route the requests for the /todo
path. We open the file server.go
and update the function newMux()
by defining
a new variable, mu
, as a pointer to a sync.Mutex
type. The pointer to Mutex
implements
the interface sync.Locker
, so we can use it as an input to the todoRouter()
function.
Then we use the variables mu
and todoFile
to run the function todoRouter()
, assigning
its output to a variable t
. Finally, we use the variable t
in the function http.StripPrefix()

prefix from the URL path, passing its output to the method
m.Handle()
to handle requests to the /todo
route. The complete, new version of
newMux()
