JavaScript objects group related data and functions together. Instead of using separate variables, you use key-value pairs.

Think of an entity like a student. An object represents this entity in your code.

Every object has three parts:

• Entity: The thing itself (e.g., a Student).
• State: What the object has (e.g., name, age). These are properties.
• Behavior: What the object does (e.g., study). These are methods.

How to create objects:

1. Object Literal This is the most common way. You use curly braces to define the object directly. It is short and easy to read. let student = { name: "Saravanan", age: 25 };

2. Object Constructor You use the new keyword to build an object. let student = new Object(); student.name = "Saravanan";

Most developers prefer the literal method.

CRUD Operations:

You perform four basic tasks with object data:

• Create: Define a new object.
• Read: Access data using dot notation (person.name) or bracket notation (person["name"]).
• Update: Change an existing value (person.age = 26).
• Delete: Remove a property using the delete keyword (delete person.age).

Advanced Concepts:

• Methods: A function inside an object is a method. You can use shorthand syntax to write them.
• Nested Objects: An object can hold another object inside it. This helps you organize complex data like an address.
• Data Types: Objects can store strings, numbers, booleans, arrays, functions, and other objects.

Summary of an object structure:

• name: String
• age: Number
• address: Nested Object
• greet: Method (Function)
