JavaScript Objects Tutorial: Create, Update, Delete & Methods
Objects are the foundation of JavaScript. In this video, we move beyond simple variables and learn how to store complex data using Objects. We use a real-world "Bike" analogy to explain the difference between Properties (characteristics like color/weight) and Methods (actions like start/stop).
If you are learning automation, understanding Objects is crucial because JSON data, API responses, and Page Object Models all rely on this structure.

To follow along, you will need:
Visual Studio Code (VS Code)
Node.js installed
Basic understanding of variables (Watch previous video)
Why is this important for QA?
When writing test scripts, you will often need to manage test data (like a "User" object with username/password) or handle API responses (which usually come in JSON format, similar to JS Objects).
