Beyond Pixel Pushing: Exploring Chrome Performance, Concurrency, and Modern Frontend Tools

Frontend development is often dismissed as mere "cut‑image" work that requires no understanding of computer fundamentals, algorithms, or high‑concurrency systems.

Chrome 87 Performance Boost

On November 17, 2020, Chrome released version 87, which the product director described as the most significant performance improvement in years. The article encourages readers to explore the release notes to understand the underlying enhancements.

Fundamentals of Computer Operation

A beginner‑friendly explanation shows how basic logic gates ( AND, NOT, OR, XOR) and arithmetic units ( ADD, ALU) work together. The accompanying video uses vivid examples to illustrate these concepts, with a promise of a future article on memory operation.

Frontend Frameworks

Page‑Level Component Library Based on Ant Design

Ant Design offers many basic components, but real‑world projects often require additional, repetitive logic. The article introduces ProComponents, a heavy‑weight component library that abstracts page‑level behavior, reducing the need to manage numerous state‑related actions manually.

Backend Development

Understanding Concurrency Programming (≈20k words, 40 diagrams)

The piece provides a comprehensive overview of concurrency: its history, processes vs. threads, concurrency vs. parallelism, common pitfalls, thread safety, locks, and priority handling. It includes clear Java code snippets to demonstrate each concept.

Tool Recommendations
