Tips for Writing Clean Code

Write readable code : Use proper indentation, line breaks, and spacing to improve structure and make the code easier to understand.

Use meaningful names for variables, functions, and methods; keep names concise (typically three to four words) while describing their purpose.

Make each function do one thing : Follow the single‑responsibility principle, treating functions as pure functions that perform a single task.

Explain intent with comments when necessary, especially for quick fixes or non‑standard solutions, so others understand the reasoning behind the code.

Maintain consistent coding style across projects by adopting a style guide and sticking to it, which eases future code navigation.

Regularly review and refactor your code to keep it clean, up‑to‑date, and free of technical debt.
