As my classmate said, I’m currently experiencing a situation of “being forced to code”… The several websites I maintain each have their own frontend, backend databases, and some even have test code and migration code, involving languages ranging from Python commonly used in bioinformatics to JS, TS, HTML, C#, which I rarely used before. In actual work, there isn’t much time to systematically learn each language from scratch, so mastering the most basic debugging methods is crucial. Among them, I find the debugging methods for JavaScript and TypeScript particularly worth recording, as they do have some unique aspects compared to other languages.
