When programmers write code, they usually use their brains to think, but they also need to refer to relevant documents, code libraries, and online resources for inspiration and help. Writing code was like writing an article. It required thinking, planning, and writing. The difference was that programmers needed to realize their ideas in code, while literati focused more on expression and creation. It was also common to look up information while writing code, especially when there was a need to quickly iterate and develop new functions. Through reading information, programmers can learn new knowledge, concepts, and techniques and apply them to code to improve code quality and efficiency. Writing code and writing articles required constant practice and tempering to gradually reach a level of fluency. A programmer needed to constantly learn, practice, and reflect in order to continuously improve their programming skills and writing skills.
