Enough JavaScript to get you Started : #10 Objects

Everything is Object in JS

What are Objects ?

👉 Let's forgot about JS objects and talk about real world objects , every object in real world have certain properties and behaviors.

👉For Example : Girlfriend 😁 , yes ! girlfriend is object , girlfriend have properties like hairColor,eyeColor,name,number,address,likes,dislikes etc...

👉 In JavaScript Object can be defined as group of related properties.

👉 Grouping all the related properties to one thing (ex. Car, GF) makes much more sense , because now it's all stored in one place and is easy to access.

👉 Objects come under category of composite data type , which means mix and match of primitive data types.

How Objects work?

👉 as we can see we grouped all the related properties under one variable namely girlfriend

👉An object is a collection of properties, and a property is an association between a name (or key) and a value.

Before making object keep in mind

👉 Objects always work in key value pair [eg. name:"john"]

👉 Arrays are always objects in JS.

👉 Functions are always objects in JS.

👉 Objects are always embedded in curly braces {}

Syntax

var object = {
      property : value,
      property2: value,
      ....
}

The Girlfriend Object 😍

let girlFriend = {
     name : "alexa",
     surname : "grace",
     likes: ["reading","football"],
     number : 123456789
}

👉 We can access object properties using "."

👉 For Example girlFriend.name gives output "alexa"

👉 girlFriend.likes gives us array ["reading","football"] as output
