These tips will help you keep your code clean, simple, and straightforward. This does not mean that you need to apply all the tips to keep your code clean. If you follow a few of the tips below, it will be enough to give you the desired results.
Readable code
As you know, the code we write is further interpreted by machines. If there are no errors in the code, then the machine can read it. But, there is always the possibility that someone else will want to work with it. Or even if you write the code purely for yourself, and no one will have access to it, then it may be that you will return to it. Therefore, it is in our best interest to write clean code from the first character.
One of the easiest ways is to use spaces and tabs. We can use code markers (blank lines, brackets, indentation) to make our code structure more readable. This will greatly improve the readability and understanding of the code.
Using clear words to assign variables, functions, methods
The essence of this advice is that you use such words for the names of variables, functions and methods, so that by looking at it, not only we, but also other developers could understand the purpose of this or that variable, function, or method. Simply put – the name should speak for itself.
Write code like this so that your function or method only performs one task
You shouldn’t write functions and methods that do a lot of things. Writing a function or method that does everything at once can lead to some difficulties, for example:
-
come up with a name that will be suitable for her;
-
few people, except you, will be able to understand what this method or function performs;
-
even you will find it difficult to understand what you wrote;
-
confusing code;
If you divide your large functions into small ones, for each separate task, then this will give you advantages, for example:
-
people will be able to understand your code, or they will need much less time to do this;
-
names will be easier to come up with;
-
functions and methods will be more predictable.
Use comments and explanations
You could get very serious about method naming and function, but for some, this is still not enough, they still do not understand your code enough. And the problem may be that it is not clear why you implemented this or that function/method. The developer who looks at your code does not understand the meaning and ideas of why it should be so.
Sometimes you have to resort to non-standard approaches to solving problems, and there is no time to solve it. And here’s the hardest part, to explain it with code. Here are the comments inside the code that can help explain to each developer why we wrote what we wrote and why so. Besides, after reading our comments, other developers will be able to suggest their solution to this problem and improve our code.
