Arrays are defined in four ways

Using the constructor:

var a = new Array(); var b = new Array(10); var c = new Array(“first”, “second”, “third”);

Or array direct quantity:

var d = [“first”, “second”, “third”];

Extension:

function ObjStory(id,biaoti,author,type) // Declare an object
{
    this.ID = id;
    this.Biaoti= biaoti;
    this.Author= author;
    this.Type = type;


}

var arr = new Array();// Declare an array to store header information

var writer= new ObjStory(11, 'Everybody go to see the sea ', 'Li Dadan ', 'Literature and art ');// Declare an object
arr[0]=writer;// To add an object to a collection

Another method:

var Array=[];

Array. push (new ObjStory (12, ‘Let’s see the sea’, ‘Li Dadan’, ‘Literature and art’));

Array. push (new ObjStory (14, ‘Let’s see the sky’, ‘Li Xiaodan’, ‘Literature and art’));
