Is refactoring worth it?

[HarryGrow]

Hello everyone, I write code for applications and spend a lot of time on errors that appear, the question arises about code refactoring. Many people say that this is useful for the cleanliness of the code and for its support in the future. Who does refactoring and how does it really help? Should it be used on a permanent basis?
I also heard about spervises that help with refactoring and code analysis, who uses it?

Tell me, is it possible to make several unique codes from one program code? In order not to waste time writing new code for the topic that has already been written

Keeping your code in one file may make it easier to write (to begin with), but as you write more, code it will make it much more difficult to read and modify. Splitting your code into multiple files is a good way to produce smaller, more focused files and navigating theses smaller files will be easier and so will understanding the content of each of these files.

2 cents.

I was advised by the AppRefactoring service to work with the code, refactor and obfuscate it. What can you say about this service?
