How to define an array of objects in javascript

The problem is as follows: a simple application of a single object has been completed, hoping to define an array that can contain multiple students.

The code copy is as follows: var student = new Object();

student.name = "Lanny";

student.age = "25";

student.location = "China";

var json = JSON.stringify(student);

Method 1:

The code copy is as follows: 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:

The code copy is as follows: var student = new Object();

student.name = "Lanny";

student.age = "25";

student.location = "China";

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

var json = JSON.stringify(students);
