Many software developers have learned programming. But without even learning its principles and foundations that make the code more organized, readable and understandable. So a lot of the code seems complex and difficult to understand and it is cumbersome to review and fix its errors. Programming principles every programmer should know for more information in this article.
1. Software developers often lack knowledge of programming principles, resulting in complex and hard-to-understand code.
2. Understanding the entire code, its structure, and the role of variables is crucial for writing clean code.
3. Programming is like completing a novel, where variables are characters with specific functions.
4. Clarity in code is essential to prevent it from becoming a nightmare to work with.
5. Writing perfect and clean code can be challenging but is important for code quality and effectiveness.
6. Bad code can be messy, have redundant variables, lack cohesion, or fail with different inputs.
7. Follow programming principles to become a better programmer and improve the quality of your code.
Separate tasks and don’t group them in one place
Try as much as possible to ensure that every function or every first class every file does one job. By avoiding stacking jobs in one place, you can reduce the size of the code. Additionally, it makes it easier for the programmer to follow and understand the code. Consequently, this facilitates the process of maintenance and provides smooth access to the location of errors and repairs.
It is also crucial to consider that functions should not be dependent on each other. For instance, the part of the code that deals with the database does not necessarily need to know how to display this data on the browser. By maintaining this separation, modifying one of them will not require modifying the other in tandem. As a result, you end up with a codebase that is easy to adjust and repair, enhancing overall maintainability.
Make it simple!
Make your code simple and generic. Additionally, don’t try to complicate things and appear like a programmer who can write complex code. Remember, you are not programming to impress anyone. If you can write what is required in one line, then do it! Furthermore, make variable names clear and meaningful. Moreover, make use of the available ready-made libraries, as this is one way to learn programming.
Another important aspect is to make your code reusable. This way, you and other programmers can make use of it in multiple programs without modifying the original code. Avoid branching out to situations that obviously won’t happen and adding solutions to problems that don’t exist. Keep in mind that your code will need maintenance. The more lines of code you have, the more testing and maintenance you will need.
If your code needs long lines of notes to explain what you’re doing, it may be because it’s a bit complicated. Therefore, you’ll need to review it and try to rewrite it in an easier and more meaningful way. This can often be due to errors in the design process, such as choosing the right model for your programming problem or selecting an algorithm that isn’t quite suitable for your needs.
Write notes on only what is necessary
Comments and notes on the code are important. However, it’s crucial not to overuse them or place them on every part of the code. Instead, try to choose appropriate places where the code may seem unclear or to justify the inclusion of unusual code. It is always preferable to have a note at the beginning of the code to explain its purpose, contents, authorship, and the date it was written. This introductory note will make it easier for you to understand the code when you revisit it after a period of time. It saves you from having to read the entire code and follow it line by line to regain understanding.
Test your code and make sure it’s of good quality
Run many tests and experiments on your code. Replace manual tests with automated test programs. Learn these systems well and use them often.
Don’t repeat your code
If you have a variable value that is repeated more than once in your code, make it a global constant that can be accessed from more than one place.
Refine your code
The first version of your code doesn’t have to be perfect. It’s normal to revise it more than once as your code is constantly evolving. It’s completely acceptable to review your work and strive to improve it as much as possible, or even consider rewriting it. This process is not a disadvantage; instead, it allows you to identify areas that can be shortened or enhanced to make your code more effective. However, ensure that your modifications align with the required outcomes.
Ultimately, your role as a programmer extends beyond writing code that functions well. Always keep in mind that you are writing code for other programmers, not just for machines. Consequently, your code should not be set in stone; it needs to be flexible, simple, scalable, modifiable, and additive. Additionally, remember that being a good programmer implies producing code that is easily readable and understandable by others.
