A collection of the Baixing.com tech team's insights and learnings, featuring one weekly technical article worth following.
This article explains why the ESLint no-fallthrough and no-undef rules exist, shows how switch case fall‑through can cause bugs, and provides practical ways—using comments or local variables—to silence warnings while keeping code clean and maintainable.
This article explains ESLint’s no‑empty and no‑empty-function rules, showing how to fix empty blocks by inverting conditions, adding comments, handling silent failures, and using intentional no‑op functions or proper callbacks to keep JavaScript code clean and readable.
This article explains the ESLint rules no‑return‑assign and no‑constant‑condition, shows why they trigger, provides clear examples of problematic code, and offers practical refactoring techniques to resolve the warnings while keeping JavaScript code clean and intention‑clear.
This article explains why ESLint’s eqeqeq, no‑bitwise, and no‑implicit‑coercion rules require manual fixes, demonstrates the pitfalls of using ==, !=, and bitwise operators, and provides clear code examples showing how to replace them with safer, more readable alternatives.
This article explains comprehensive methods for testing lottery modules—including probability verification, high‑concurrency simulation with JMeter, and real‑time data monitoring using Grafana—to ensure stable, accurate prize distribution during large‑scale promotional events.
This article explains how to avoid data races in high‑traffic distributed systems by comparing pessimistic and optimistic concurrency control, demonstrating RDBMS row locks and a Redis‑based distributed lock implementation with Python code examples.
This article shares practical strategies for designing, dividing, and managing React components in a large‑scale CRM system, covering component hierarchy, state and props handling, data communication, common pitfalls, and best practices to improve maintainability and performance.
This article explains how IGListKit can replace cumbersome UICollectionView data‑source code with a data‑driven framework, showing step‑by‑step Swift examples for building a two‑column video grid, handling ads, animations, diffing, and advanced section controllers.
This article explains how refactoring the Baixing Android app’s list feature from an inheritance-heavy design to a composition-based architecture improves modularity, reduces coupling, and eases future extensions by applying OOP principles such as dependency inversion and component interfaces.
Test Fest is a company‑wide, short‑duration crowdsourced testing event that brings product managers, developers, designers, operations, and support staff together to explore a product, uncover bugs, improve compatibility, and generate actionable insights, dramatically boosting testing efficiency and ROI.
