Four Types of Code Hygiene: Understanding Programmers' Clean‑Code Habits

Many programmers develop unique habits while writing code, and a common one is a strong sense of "code hygiene".

The author’s brother collected several symptoms of code hygiene and categorized them into four types.

1. Minimalist (极简断舍离) Type

2. Distance‑Creates‑Beauty (距离产生美) Type

3. Precise‑Constraint (精准约束) Type

4. Creative‑Craft (别具匠心) Type

Seeing such extreme pursuit of perfection, the brother expresses admiration.

Having code hygiene is not a bad thing; as quoted from *The Pragmatic Programmer* (《程序员修炼之道》): "Don’t live with broken windows" – when you encounter bad design, wrong decisions, or poor code, you should fix them.

Although maintaining strict code hygiene can be time‑consuming, it brings great benefits later in a project: easier business expansion, onboarding new teammates, reusing functionality, and tracing bugs, thereby significantly improving team efficiency.

In the real world, technical debt will eventually have to be repaid.

If code becomes too messy, even the original author may not understand it after a few months.

The article invites readers to share their own code‑hygiene habits in the comments.
