Apostolate of the Good Code

[mostakimvip06]

Before answering the question, it is necessary to explain what clean code is ? This term does not have a clearly defined definition. It is a certain idea, practice, according to which the code should be easy to edit and understand . But to say only this is like saying nothing. Another question arises - what does it mean that the code is understandable?

How to understand the code?
The truth is that the code of a website or program is not written for the client, but for subsequent developers and programmers who will use it. Without the appropriate experience and knowledge of the language in which it is written, even the best code may be incomprehensible. But it doesn't have to be! The most important rule of clean code is that it should be readable and self-commenting . A rich source of knowledge about correct and pleasant to work with code is Robert C. Martin's book entitled "Clean Code. The Good Programmer's Handbook" . On its basis, certain recommendations can be formulated, the application of which will allow the creation of clean code.

Judge the code by its cover
The easiest way for almost anyone to evaluate code is to evaluate its formatting . It is worth noting that only unminified and uncompiled code is evaluated, i.e. code that is used for work, not code that will ultimately end up on a website or in a program. The most important rules that every code should meet include:

small files/classes are better than large ones
spaces between code segments
the order of methods and functions should be sorted by increasing detail
lines of up to 120 characters
spaces around operators
horizontal indents separating blocks of code
consistent formatting across the team
These few points can make work incredibly easier and increase code readability . Following these rules distinguishes a programmer from a good, elegant programmer. Clean code should be elegant.

And his name is forty-four
It is extremely important that the code is self-commenting. What does this mean? It should use names of classes, methods and functions that make it clear what they are about. Therefore, these names should clearly represent australia telemarketing data the intention , avoid misinformation, and additionally should be easy to pronounce and search. In addition, the format of the name should be appropriate to the language used . There are many different notation systems , for example:

camelCase , in which words are written together and with a capital letter except for the first one, e.g.: dlugaNazwaZmiennaj - is most often used in various programming languages ​​(e.g. Java, C++) to name functions and methods
snake_case , in which words are written separately in lowercase letters, and the spaces between them are the "_" character - it is most often used in the Pascal programming language
The most important thing is that the name format is consistent for the entire team. In such a case, it is worth adopting a common naming convention . This is a set of instructions that determines how subsequent elements of the code should be named. An example is the increasingly popular BEM convention , i.e. Block - Element - Modifier. Invented for the needs of the CSS language, it definitely works well in everyday work .

Cleaner is better
It is easy to guess that clean code can significantly speed up the work of each subsequent person involved in the project. Developing such code and its modifications becomes much easier . This saves time, and therefore money. If the company we hire adheres to the principles of clean code, we can be sure that even after the end of cooperation, subsequent programmers and developers should have no problem implementing our project.

Code evaluation can be difficult, so it's worth entrusting such a task to specialists. When ordering an audit, it's worth asking about the code cleanliness assessment, because clean code is essential!
