JavaScript Objects: Creation and Core Methods
🎥 JavaScript Objects: Creation and Core Methods | JavaScript for Beginners – Ep 9
In this episode, we dive into the *foundation of structured data in JavaScript* — the **object**. JavaScript objects allow you to group related data and behavior in powerful, flexible ways. This video shows you how to create, use, and manipulate them confidently.

What You’ll Learn:
What are objects in JavaScript?
Creating objects using literals and constructors
Understanding key-value pairs
Accessing properties with dot and bracket notation
Adding, updating, and deleting properties
Nesting objects and accessing deep values
Looping through object properties with `for...in` and `Object.keys()`
Core object methods: `Object.assign()`, `Object.keys()`, `Object.values()`, `Object.entries()`
Differences between reference and primitive data types
Real-world examples of when and how to use objects

Why This Matters:
Objects are everywhere in JavaScript — in arrays, DOM elements, APIs, and even functions. Mastering them unlocks the ability to build **real applications**, work with **JSON**, and design clean, maintainable code structures.

Practice With:
Creating user and product objects
Iterating over dynamic object data
Merging and copying objects with built-in methods
