Object:
- A collection of related data and/or functionality, consisting of properties (key-value pairs) and methods (functions).
Property:
- A key-value pair within an object, where the key is a string (or symbol) and the value can be any data type.
Object Literal:
- A syntax for creating objects using curly braces {} with key-value pairs.
Dot Notation:
- A method of accessing object properties using a dot . followed by the property name (e.g., object.property).
Bracket Notation:
- A method of accessing object properties using square brackets [] and the property name as a string or variable (e.g., object["property"]).
Method:
- A function that is a property of an object, used to perform actions related to the object.
delete Keyword:
- An operator used to remove a property from an object.
Dynamic Property Access:
- Accessing object properties using variables or expressions, allowing for flexible property manipulation.

Early JavaScript Development (1995): Introduced objects as a way to group related data and functionality, enabling more structured and organized code compared to purely procedural programming.
Prototype-Based Inheritance:
- JavaScript uses prototype-based inheritance, allowing objects to inherit properties and methods from other objects, facilitating code reuse and the creation of complex data models.
Enhancements with ES6 and Beyond (2015+): ES6 introduced classes, providing a more familiar syntax for object-oriented programming while maintaining JavaScript's prototype-based inheritance under the hood.
Modern Usage: Objects remain a core part of JavaScript, essential for everything from simple data storage to complex application architectures in both front-end and back-end development.

First-Class Objects:
- In JavaScript, objects are first-class citizens, meaning they can be assigned to variables, passed as arguments to functions, and returned from functions.
Dynamic Nature:
- Objects in JavaScript are dynamic, allowing properties to be added, modified, or deleted at runtime.
Nested Objects:
- Objects can contain other objects as properties, enabling the creation of complex, multi-level data structures.
this Keyword:
- Within object methods, the this keyword refers to the object itself, allowing methods to access and manipulate the object's properties.
JSON Compatibility:
- JavaScript Objects Notation (JSON) is a widely used data format that is based on JavaScript object syntax, facilitating data exchange between servers and web applications.
