The path of advanced programming expert in refactoring

Definition of refactoring:

Refactoring is a kind of adjustment to the internal structure of software without changing the observable behavior of software.

The goal of refactoring:

1. The code is easy to read.

2. All logic is specified only in the only place.

3. The new changes will not be a crisis to existing behaviour.

4. Express the conditional logic as simple as possible.

The difference between refactoring and rewriting:

Refactoring does not change the external results, but only adjusts the internal structure;

Rewriting is a re-engineering, which may produce different external results.

Questioning about the death of refactoring:

Refactoring has its own historical conditions and scenarios, and we should not misuse refactoring.

The taste and refactoring of bad code mentioned in the refactoring book is a summary of many years of experience for others, and many good suggestions for improving the code are provided.

Refactoring is definitely a tool for beginners with code-style immaturity, and after several refactoring you are amazed to find that your code is becoming more and more prescriptive.
