为什么只输出 一个班级?
var klass=require('./klass')
exports.add=function(klasses){
klasses.forEach(function(item,index){
var _klass=item
var teacherName=item.teacherName
var students=item.students
})
klass.add(teacherName,students);
}
exports.add([teacherName='mars',students=['黑穷丑','矮穷矬'],teacherName='mars',students=['小红','小明']])
