nodeJSモジュールの簡単な使い方

function add(student){
  console.log('Add Student:'+student);
}
exports.add=add;
function add(teacher){
  console.log('Add Teacher:'+teacher);
}
exports.add=add;

//引入student模块
var student=require('./student');
//引入teacher模块
var teacher=require('./teacher.js');
function add(teacherName,students){
 teacher.add(teacherName);
 students.forEach(function(item,index){
  student.add(item);
 });
}
//向模块对象，注册方法
exports.add=add;

var class1=require('./kclass.js');
class1.add('高一班',['张三','李四']);
