A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function's scope from an inner function.
end() before the callback is triggered, because Closing the connection is done using end() which makes sure all remaining queries are executed before sending a quit packet to the mysql server.
server. close() prevents new connections and waits until all the clients are closed. To forcibly kill a node server you need to call server. close() and then close all the open connections from the server end.
Closures are important because they control what is and isn't in scope in a particular function, along with which variables are shared between sibling functions in the same containing scope.
