Always keep your head up

Anyone can become a coder, but to become a good coder, you need to work hard. That is when things get tough.

Coding is not as easy as you think it to be.  It is common to make mistakes while learning coding. Just like any other subject, it takes time and dedication for you to learn it. If you want to be successful, you cannot settle for codes that work. You need to aim for more. In other words, you should be able to write codes that can be maintained. Not just you but even others should be able to use your code while using the software. Several principles of programming can help you get better with your skills.

Principles of Programming

Here are some basic principles of programming that every programmer should know about.

  1. Keep it simple
    Just because you know coding doesn’t mean you have to make things complicated. You should keep your code simple. This is particularly more important when your code is going to be used by others as well. When you know what you want to create, the process becomes much easier. Keeping it simple, however, doesn’t mean that you will create something useless.

  2. Don’t repeat yourself
    This is one important principle that every programmer should follow. This is important to make your code easy to modify. When writing code, you should not resort to duplication. If you start writing the same code, again and again, you are breaking this principle.

  3. Single responsibility
    According to this principle, ever module or class in a program should provide at least a single specific functionality. Modules or classes start in a very simple way, but as you start adding more features and behaviors in it, it evolves into good modules and classes. They then take up hundreds and thousands of lines of code. This is when it is required for you to break them into smaller modules and classes.

  4. YAGNI
    This stands for You Aren’t Gonna Need It principle. This states that you should not code for getting the functionality that you may need in the future. There are high chances that you won’t be needing at all, and thus, you will only waste your time creating it. Not just that, but it also makes your code unnecessarily more complex.

So these are some of the basic principles that every programmer should follow. This is important only when you want to become a good programmer.
