Content: Common functions, anonymous functions, how the function is passed to the HTTP server to work

# # #普通函数
Example:

function Say (Word) {  console.log (word);} function Execute (someFunction, value) {  "Hello");

# # #匿名函数

function Execute (someFunction, value) {  someFunction (value);} Execute (function(word) {Console.log (Word)}, "Hello");

function passing is how to get the HTTP server to work
With this knowledge, let's take a look at our simple and not simple HTTP server:

var http = require ("http"); Http.createserver (function(request, response) {  Response.writehead ($, {"Content-type": "Text/plain"});  Response.Write ("Hello World");  Response.End ();}). Listen (8888);

Now it should look a lot clearer: we passed an anonymous function to the Createserver function.
This code can also be used to achieve the same purpose:

var http = require ("http"); function onrequest (Request, Response) {  Response.writehead ($, {"Content-type": "Text/plain"});  Response.Write ("Hello World");  Response.End ();} Http.createserver (ONrequest). Listen (8888);
