Software is done in cooperation with each other, by different people to complete the process of the software, because the code of different style specifications, such as indentation, line width, parentheses, line breaks and so on, reading other people's code will have a generation gap; In addition to these style specifications, when you complete a small function, to deal with the logical relationship of the code, Because the code is to show to others, if the code is not very readable, when others use your code, because the structure of chaos still has to spend time to study your code, so it is better to re-implement it again, perhaps more than the time to study your code is shorter.
When you complete the code, but also to review the code, the most basic review is the peer review. Code review can find out some minor errors and correct them, avoid the late due to this small error caused large errors, and, such a small error, the more the cost of later repair.
After the code review, correct the errors can be corrected, corrected, the error recorded in the project management software, but also to record their mistakes, as the first step in the future self-review.
