This document provides an introduction and overview of Node.js basics. It discusses Node.js, JavaScript, and Java. It outlines the course topics of Node.js and MySQL, real-time applications, and NoSQL. It also lists some prerequisite skills and notes about Node.js. Key aspects of Node.js discussed include being non-blocking, event-driven, and supporting high concurrency. The document also demonstrates requiring modules and the CommonJS module pattern in Node.js code examples.

58. var monther = require('monther');
monther.on(' ', function ( ){
return ;
});

59. var monther = require('monther');
monther.on(' ', function ( ){
return ;
});

60. var monther = require('monther');
monther.on(' ', function ( ){
return ;
});

61. var monther = require('monther');
monther.on('cofee', function (data) {
return data;
});
monther.on('egg', function (egg) {
return egg;
});
monther.on('cake', function (cake) {
return cake;
});

62. REQUIRE???

64. REQUIRE
=
LOAD MODULE

66. <script src=‘xxx’>

67. <script src=‘xxx’>
<script src=‘jquery.js’></script>

68. var xxxx=require(‘xxx’);

69. var xxxx=require(‘xxx’);

70. var xxxx=require(‘xxx’);
var http = require(‘http’);

71. var xxxx=require(‘xxx’);
var http = require(‘http’);

72. var xxxx=require(‘xxx’);
var http = require(‘http.js’);
var http = require(‘http’);

73. var xxxx=require(‘xxx’);
var http = require(‘http.js’);
var http = require(‘http’);

74. var xxxx=require(‘xxx’);
var http = require(‘http.js’);
var http = require(‘http’);

75. var xxxx=require(‘xxx’);
var http = require(‘http.js’);
var http = require(‘http’);

76. new.js old.js
