"The beauty of simplicity"--the 3 misunderstandings of software design in the way of software design

First, to write unnecessary code

1. You should not write those code before real demand comes.

2. Do not write unnecessary code, and delete unused code.

Second, the code is difficult to modify

1, make too many assumptions about the future.

2. Write code without careful design (basic design is not done)

3, the design process should be based on what you now know exactly what needs, rather than what you think the future will arise.

Iii. Excessive pursuit of universal

1, if your code is very general, it is usually not from the user's point of view to meet the specifications/requirements.

2, too much general need to write a lot of unnecessary code.
