Clean Code Principles for Junior Developers

Clean code is not about being clever. It is about being clear.

Name things for humans

`getUserById` beats `fetchData`. `SchoolFeePayment` beats `Obj2`. Future you will thank present you.

Keep functions focused

One function, one job. If you need "and" in the description, split it.

Folder structure reflects domains

Group by feature (`/students`, `/fees`), not by file type alone. Co-location reduces cognitive load.

Pull requests are documentation

Small PRs. Clear descriptions. Your PR is how senior engineers judge your thinking.

These habits compound. Start now.
