Node简单的模块化小例子

模块化解决了JavaScript作用域互相污染问题，这里以写一个学校小例子，便于理解node的这个写法和一些简单的API（比如forEach这个.....）。

 文件：

依次student.js,teacher.js,kclass.js(class为保留字，不能命名),index.js,school.js

function add(student) {
    console.log('Add student:' + student)
}

exports.add = add

function add(teacher) {
    console.log('Add teacher:' + teacher)
}

exports.add = add

var student = require('./student')
var teacher = require('./teacher')

function add(teacherName, students) {
    teacher.add(teacherName)

    students.forEach(function(item, index) {
        student.add(item)
    })
}

exports.add = add

var kclass = require('./kclass')

exports.add = function(kclasses) {
    kclasses.forEach(function(item,index) {
        var _klass = item
        var teacherName = item.teacherName
        var students = item.students

        kclass.add(teacherName, students)
    })
}

var school = require('./index.js')

var classesArr = [
    {
        'teacherName':'Bob',
        'students':['SB1','SB2']
    }
];

school.add(classesArr);
