Front-End System Design

• Understand Core UI Fundamentals: Learn the essentials of the box model, browser rendering, DOM manipulation, and state management for creating efficient front-end systems.
• Optimize Performance: Gain skills in improving UI performance through virtualization techniques and understanding browser rendering and composition layers.
• Master Web APIs: Explore the Observer API, including IntersectionObserver and ResizeObserver, for building complex UI patterns like infinite scrolling.
• Design Scalable Interfaces: Learn how to design scalable and responsive user interfaces using modern CSS layout techniques such as Flexbox and Grid.
• Prepare for System Design Interviews: Practice designing a social media news feed in a simulated system design interview, applying best practices in application state management and API communication.

This course dives into front-end system design, focusing on creating scalable and efficient user interfaces. You'll master core UI concepts such as the box model, DOM manipulation, and performance optimization techniques. The course includes hands-on exercises like building an infinite scrolling feature using IntersectionObserver and concludes with a simulated design interview exercise, where you'll design a social media news feed.
