Reasons Why These Four “Clean Code” Tips Can Improve Your Coding Skills

Software development is like a building block where every little development must be clean and well placed.

In software development, it is always good to think of scaling up the project and you may find it difficult to scale up a project even it is a ‘spaghetti” codebase.

Implementing “clean code” practices will double the progress and growth of the project success on the long run and at the same time, it will improve the moral of the whole engineering team working on such project.

To fully practice the four “clean code” tips, you need to be embracing these listed points below:

1. Have I tested the code?
2. Did I choose meaningful names?
3. How long is my functions and classes?
4. Never modify user input?

Grab a cup of tea and let me take you through the point one after the other and start applying each of them in your engineering teams.

HAVE I TESTED THE CODE

That moment when you are demoing a project that you have took over 2 months to develop and later discussed that one bug was leading to another.

Always write a lot of tests even if it is unit tests because it helps. Before integrating any tests, think twice even thrice to make sure that you covered all the core business functionality.

The moment that once there are no test coverage for a piece of code, the tendency to fail in your project is really high because you will never know until your customers find the bug in the application.

Always sing the song of “have you tested your code” to your engineering team until you are sure that the practice sinks into their daily programming coding routine.

Tell them to always practice it even when the engineer is just fresh and out of university.

DID I CHOOSE MEANINGFUL NAMES

You have heard many times without numbers on the saying “Never pick a bad name” and it is now becoming much relevant every single day in the life of computer programmer.

Let me break it to you today, if your team is good in naming convention, it will be a maintainable success.

You will as well close many of your best developers

Seriously, don’t pick names that is not related to what you are programming about.

Pick a short name and precise, if they might be in conflict, use long meaningful names

HOW LONG IS MY FUNCTIONS AND CLASSES

Functions and classes are the user-defined keywords which enables programmers to extend the functionalities of their programs. Many functions and classes are the backbone of my frameworks and projects, they are introduced into programming to make it easier for programmers to use and feel the coding the way they like.

What does “small” mean for functions? No more than 4 lines of code. Yep, you read that correctly, 4 lines. You’re probably closing the tab right now but you really shouldn’t. It seems somewhat arbitrary and small and you’ve probably never written code like that in your life. However, 4-line functions force you to think hard and pick a lot of really good names for sub-functions that make your code self-documenting. Additionally, they mean you can’t use nested IF statements that force you to do mental gymnastics to understand all the code paths.
