I’ve been working with Sencha Ext JS for a while and am particularly interested in its component-based architecture, which is one of its most powerful features. However, I’ve encountered some challenges in fully understanding how to effectively use and extend components, especially when it comes to building complex UI applications.

I’m finding the learning resources for Sencha Ext JS to be somewhat limited, and I’m looking for frameworks with similar architectural patterns to help deepen my understanding of these concepts.

The Specific Problem:
While working with Sencha Ext JS, I’ve been trying to tackle the following issues:

Create Custom Components: I want to create custom components that extend existing ones, but I’m having trouble understanding the best practices for doing so without introducing performance issues or breaking encapsulation.

Data Binding and Management: Managing data efficiently within components has been tricky. I’m unsure how to properly set up data stores and bind them to my components in a way that ensures data consistency and reactivity.

Component Lifecycle: I’m struggling with the component lifecycle methods and when to appropriately use them to manipulate the DOM or perform asynchronous operations.

What I’ve Tried:
Official Documentation: I’ve read through the official Sencha Ext JS documentation and tried to follow some example code, but the resources seem limited when it comes to more complex, real-world scenarios.

Online Tutorials: I’ve watched introductory tutorials but still feel unclear about the nuances of component interactions and state management in larger applications.

What I Am Seeking:
Frameworks with Similar Concepts: I’m looking for frameworks that offer similar component-based architectures and patterns. The goal is to understand these concepts better, which could provide insights that apply to mastering Ext JS.

Best Practices: I would appreciate advice on best practices for creating custom components, managing data efficiently, and utilizing lifecycle methods effectively.

Learning Resources: Recommendations for comprehensive learning resources, such as courses, guides, or documentation, that can aid in understanding complex UI frameworks.
