javascript How to Define an Array of Objects

The problem is as follows. I have completed the simple application of a single object, and I want to define an array that can contain multiple student.

var student = new Object(); 

student.name = "Lanny"; 

student.age = "25"; 

student.location = "China"; 

var json = JSON.stringify(student); 

Method 1:

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);

Method 2:

var student = new Object(); 

student.name = "Lanny"; 

student.age = "25"; 

student.location = "China"; 

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

var json = JSON.stringify(students);
