Arrays and Objects in JS | Codecademy
In this course, we'll cover some of the more powerful features of JavaScript in greater detail. We'll review arrays, create arrays of arrays, and begin learning about a new data structures: objects.
Three. Introduction to Objects
File1 _ script.js
var phonebookEntry = {};
phonebookEntry.name = 'Oxnard Montalvo';
var phonebookEntry = {};
phonebookEntry.name = 'Oxnard Montalvo';
phonebookEntry.number = '(555) 555-5555';
phonebookEntry.phone = function() {
console.log('Calling ' + this.name + ' at ' + this.number + '...');
};
phonebookEntry.phone();
10/17 Object syntax
File1 _ script.js
var me = {
name: "JONE",
age: 35,
}
console.log(me);
11/17 Creating a new object
File1 _ script.js
var me = new Object();
me.name = "JONE";
me.age = 35;
console.log(me);
12/17 Practice makes perfect
File1 _ script.js
var object1 = {a: 1,
b: 2,
c: 3
};
var object2 = {};
object2.a = 1;
object2['b'] = 2;
object2.c = 3;
var object3 = new Object();
object3.d = 4;
object3.e = 5;
object3['f'] = 6;
console.log(object1);
console.log(object2);
console.log(object3);
