javascript如何定义对象数组

问题如下，已经完成单个对象的简单应用，希望定义一个数组，能包含多个student。

var student = new Object(); 

student.name = "Lanny"; 

student.age = "25"; 

student.location = "China"; 

var json = JSON.stringify(student);

方法一：

var students = [];

students[students.length] = new Object(); 

students[students.length].name = "Lanny"; 

students[students.length].age = "25"; 

students[students.length].location = "China"; 

var json = JSON.stringify(students);

方法二：

var student = new Object(); 

student.name = "Lanny"; 

student.age = "25"; 

student.location = "China"; 

students = (students || []).push(student);

var json = JSON.stringify(students);
