The first challenge encountered at the start of the programming is to write functional code. But after becoming a developer, programming skills will grow. Your code should function code from the ordinary development of simple, efficient, understandable and maintainable code.

This is the real challenge faced by developers.

This article will introduce five principles to help you achieve super status code.

1. Code glance

When increasing the size of the program, code complexity will increase. The code will become difficult to debug because debugging complex code is a daunting task. No one likes to maintain complex code. This principle states that you should always keep it simple code. If the code is complicated, please do your best to break down into smaller, more maintainable code.

Write clean code is more difficult than writing complex BS code. As a developer, along with the skills continues to mature, your code should be more clean, more meaningful.

2. You do not need it

Sometimes you should take precautions, but not in programming. People tend to write code may require future but now is not needed. These codes unnecessarily increases the size of the program, because the code is written never materialized. More importantly, most programmers will not use these codes in the future. Programmers of this habit will bloat unnecessarily.

The implementation of the principles laid down when necessary. This is a recommended every developer should follow.

3. Do not repeat

这一原则对于编写简单且易于修改的代码至关重要。重复的代码是程序员常犯的错误。这个原则指出，一段代码应该在源代码中的一个地方实现。如果注意到同样的代码块重复出现，说明违背了这个原则。

这一概念的反义词为WET代码：所有内容都重复一遍

可以创建一个公共函数或将代码抽象化，以避免代码中的任何重复。

4.关注点分离（SoC）

关注点分离原则：管好自己的事——就是字面意思。这个原则建议将复杂的代码划分为不同的部分或域。每个部分相互独立，因此每个部分可以独立处理。而且，维护、更新和重用代码也更加容易。

SoC一个很好的例子就是MVC架构。该架构将程序分成三个区域：数据（模型）、逻辑（控制器）和最终用户看到的内容（视图）。MVC在现代框架中大量运用。
