45 Simple Tips You Can Follow To Write Clean And Better Code. I keep seeing totally confusing source code. It is always difficult to understand even my own code later on. Also, you can easily destroy something or “just” slow it down.

Because If the code is easy to understand, it’s easy to change.

I keep seeing totally confusing source code. It is always difficult to understand even my own code later on. Also, you can easily destroy something or “just” slow it down. Since I didn’t always program properly when I started as a developer, it is difficult to revise the respective things later.

And that’s why I suggested this list so that you can keep your code clean! You can also give it to your colleagues, for example, to have advantages if you expand their code. Here we go:

  1. Don’t comment out any source code. It is best to delete it immediately. Version management will always have the old code ready.
  2. No code block may appear twice! It is even best if no code lines appear twice, but this cannot always be avoided.
  3. Don’t use constructors because in some languages, for example, you can’t serialize the object. Besides, when you use it, you never really know what is going on in the constructor. It is better to pack the things carried out there in their own functions. For example, if he should load something from the DB, the method loadFromDB can be created and executed afterward.
  4. All properties/functions etc., must be named according to the same pattern. Camel casing, for example, is a good choice here.
  5. Do not use any tools that automatically generate documentation from your code. So you really have to write a lot of comments in the source code that fill the code up. As such, functions should be meaningful in such a way that they do not require any comment.
  6. Use constants for fixed values. For example, you can specify VAT or similar in one place. Another advantage is that you can immediately see what this value is for when you look at it.
  7. Interfaces must start with an I.
  8. Interfaces may only describe one functionality (which can, however, consist of several functions).
  9. The same code in several classes should be written in abstract classes.
