A developer discovers a bug where a time component displays incorrect dates because the backend switched timestamp values from numbers to strings, and learns how to correctly parse timestamps in JavaScript using Dayjs and defensive Number conversion.
This article recounts a date‑misalignment bug caused by an unintended Day.js locale change in a mini‑program, explains why the global locale must remain unique, and details a comprehensive static‑analysis solution using ESLint, custom Webpack loaders, and Babel plugins to intercept and block Day.js locale modifications at compile time.
This article examines why native JavaScript Date falls short for time handling, explains time measurement standards and time zones, and compares four major date libraries—MomentJS, DayJS, date-fns, and native Date—highlighting their advantages, drawbacks, and appropriate usage scenarios.
This article explains the history of global time standards, how computers represent time with Unix timestamps and the 2038 problem, details ISO 8601 and RFC 2822 formats, and provides practical JavaScript Date usage examples along with comparisons of popular date‑handling libraries such as Moment.js, Dayjs, and Miment.
