Part V: Code improvement25 Code Tuning PolicyIn the 70 's, programmers realized that overly focused performance would lose the readability and maintainability of the program.For ordinary users, programmers deliver software on time, a refreshing interface, and avoid crashes, often more important than performance.Consider several issues before optimizing efficiency:1, the requirements of the program (customer

But what I want to say is: the author intentionally makes it so big that there is not so much single source code, about 3 MB.
It is not easy to interpret the source code of Ext.
But I believe many people need it!

4. It violates the open and closed principle because it must be modified whenever a new type is added. However, the most troublesome thing is that there are functions with similar structures (_ get type name Rank () everywhere.

this case, we should refine the class or refine the subclass for reconstruction.
2) If the class contains too much code, it usually means that the code is repeated. At this time, you can also use the refining class and refining subclass to reconstruct it.
3) if the large class is a GUI class, data and behavior can be separated into an independent class. You can use the repeated observation data method for
