Code reconstruction rules

The following is my personal summary of code refactoring based on the actual experience: refactoring purpose: the purpose of refactoring is to allow the code to be understood and understood by others without comments. Reconstruction principles: 1. remove duplicate code 2. if you do not understand a method, divide it into a smaller part and give them an appropriate name 3. try to make your public processing methods and functions only do one thing. 4. public processing methods and functions are short and lean 5. easy-to-read/easy-to-understand code is better than code with better performance. Simple and easy-to-understand code is the final purpose. Reference article: refactoring rules-coding
