Though operational, software code can be quite poor in quality according to several criteria. It is like a problem car — it seems to be going forward but constantly requires maintenance and may just refuse to start at any moment.
Bad code is like bad novel. It is chaotic, has an obscure structure, and it is generally difficult to get an immediate idea of what the author wanted to say.
If we try to deduce the signs of low-quality code, the list will be as follows:
- It is difficult to make sense of it;
- It has unnecessary iterations and complexities;
- The function name is unclear to show the task it solves;
- If complemented with something, code can become inoperable.
Consequently, the working software does not necessarily mean it is based on good software code. Code smells are not the problem but its symptoms.
There are several principles, following which developers can make sure that their software code meets the definition of “good.” Moreover, the more complex and large-scale the project is, the more relevant code quality is, as testing and fixing errors can be quite costly.
The developers adhering to the best practices, keeping in mind standards, conducting regular testing, and taking feedback from their colleagues into account can rest assured they will deliver the best results.
