What is Refactoring?

Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure. And it makes software easier to understand.

I think refactoring goes further because it provides a technique for cleaning up code in a more efficient and controlled manner.

  • Refactoring does “not” mean:
  • rewriting code
  • fixing bugs
  • Changing functionality
  • improve observable aspects of software such as its interface
