Objects in JavaScript (2025)

Unlock the full power of JavaScript Objects in this in-depth tutorial! 🚀 Ever wondered why objects are better than arrays for managing complex data? We'll break it down! 💡 You'll learn how to create objects from scratch, access their properties using both *dot notation* (`.`) and *bracket notation* (`[]`), and master the key differences between them. But we don't stop there! Level up your skills by making your objects perform actions with **methods**. We'll demystify the powerful `this` keyword 🧠 and build practical methods like `login`, `logout`, and even one that calculates a user's age on the fly! To wrap it all up, you'll tackle a fun challenge to create a dynamic `getSummary` method. This lesson is a critical step for any JavaScript developer.
