The importance of code specifications

The importance of code specifications

A standardized code can usually get twice the result with half the effort. In my section below: code specifications are everywhere, but few companies do a good job of code standards. I can't help but want to talk about the importance of code specifications. I hope everyone can pay attention to them.

Moreover, I believe that if our code specifications can be well done, we will have at least a lot of outstanding open-source projects, not to mention how much the development level is improved. I. Standardized Code can promote teamwork. Most projects are completed by one team,

If there is no unified code specification, everyone's code will have different styles. Not to mention the situation where multiple people develop the same module at the same time, even if the division of labor is very clear, it will be a headache to wait until the code is integrated. In most cases,

It is not a complicated algorithm or logic in the program, but a painful task to read other people's code. The unified style greatly improves the readability of the Code. People may feel unfamiliar with any piece of code. Obviously, standardized code is very beneficial and necessary in the cooperative development of the team.

Ii. Standardized Code can be reduced

Bug handling many IT professionals compare programmers with migrant workers, which is indeed a very good image. As mentioned earlier, complex algorithms or logics only account for a small proportion of projects, and most of them only work on base code. But the simpler it is, the more bugs it tests, and the endless bug. This is largely due to code irregularities.

There is no standard specification for input/output parameters, no standard exception handling, and no standard log processing, this not only causes low-level bugs like null pointers, but also makes it difficult to find the cause of the bug. On the contrary, in standard development, bugs can not only be effectively reduced, but also become easy to find.

The specification does not restrict development, but it does help improve development efficiency.

3. Standardized Code can reduce maintenance costs

With the accumulation of our project experience, we will pay more and more attention to the cost of post-maintenance. The code quality in the development process directly affects the maintenance cost. Therefore, we have to be careful during development. As mentioned in the first point, the standard code greatly improves the readability of the program, and almost all programmers have done maintenance.

Needless to say, the cost of code maintenance with high readability will inevitably be greatly reduced. However, the maintenance work is not only to understand the original code, but to make modifications based on the original code. We can first consider that, if there is no uniform style, after A completes development, B maintains and adds A piece of code.

Add a piece of code. Until one day I saw a lot of garbled and dead minds, and maintenance would not be able to proceed. Therefore, a unified style is conducive to long-term maintenance. In addition, good code specifications constrain the measurement of methods, classes, and program coupling. In this way, there will be no need to modify a method of thousands of rows or

To expand a class without interfaces. Standardized Code improves program scalability, which is undoubtedly a reward for maintenance personnel.

4. Standardized Code facilitates code review

I personally agree with the code review, which can promptly correct some errors and supervise the code specifications of developers. The Code Review of the Team is also a good learning opportunity, which is also beneficial to the progress of members. However, random development increases the workload and difficulty of code review, and makes the code review useless. This wastes a lot of time but has little effect. Code specification not only makes the development uniform, reduces the review, but also makes the code review traceable, greatly improving the review efficiency and effect. At the same time, code review also facilitates the implementation of code specifications. How happy is it.

5. develop the habit of code standardization and help programmers grow.

Even if you understand the benefits of code specifications, some of them are under project pressure. Some of them make a lot of extra work due to tedious specifications, and some do not pay attention to maintenance issues, which makes it difficult to implement code specifications. We need to know that the biggest beneficiaries of standardized development are actually ourselves! Have you spent a lot of time searching your own code? Especially with bugs

The lines-by-line debugging code is required. What we should do is standardize development to reduce errors. In many cases, the project pressure is partly due to the numerous issues left over from the preliminary development. Some people think they can complete difficult algorithms, and they think they are very competent,

Do not put standards in the eyes. This is true for many people. The pursuit of personality may make others feel more satisfied when looking at their code. Although we do not know that complex algorithms can reflect your own logic capabilities, they do not represent your development level. We know some open-source projects,

The program written by some masters is extremely standard. If it is not a standard, it indicates a high level. In fact, the Standard Code helps you understand the development language understanding mode and the architecture, and helps you quickly improve the development level. I don't understand this. Even if you write a clever algorithm, it may be treated as garbled code someday. Remember!

Every day without code (maybe you don't think, but most of the time in the eyes of others is indeed garbled) does not allow you to make more progress, on the contrary, to reach a high level of programmers, developing good development habits is absolutely necessary. Do not indulge in superficial gains and losses. Seemingly useless things will gradually accumulate from quantitative changes to qualitative changes, so that you can feel them.

Value.

Finally, I would like to remind you that it is very easy to develop a development specification that conforms to your company's situation. What is important is that we can recognize the importance of the specification and stick to the standardized development habits.
