How To Write Clean Code – Top 5 Ways

Code is the language of developers. It’s the only language that cannot be spoken and can only be communicated by hand. Being a language that cannot be spoken it is best to have it written well and in an understandable manner. Technically speaking the code must be understandable for the person that will maintain the said code.

If you are new to programming here is an article on how to learn programming faster. If you already know how to program lets move forward!

Here are the top 5 ways to write Clean code.

1.Comment Your Work

Comments are essential when it comes to writing clean code. They allow for the programmer to show what every block or even every line of code represents. Making it that much easier for the programmer to come back to the code after a while. Also in many companies the developers of a certain software are usually not the ones that maintain it hence comments allow for a new team of developers to understand how the code was written.

It is an industry best practice and is expected from every professional developer.

2.Name Them Right!

Variables are an integral part of programs. They allow for values to be stored and manipulated which is a fundamental process. In industry level programs the number of inputs and outputs are large hence needing many variables to manipulate these values. The names given to these variables must be relevant to the values they hold hence allowing for greater understanding of the code in general.

Another key point to keep in mind is the length of the variables. Making them too long would not be considered industry best practices. This is a crucial part in writing clean code.

3.Memory Optimization

Software these days needs to be highly optimized if they have to be released into the real world. Utilizing the bare minimum of variables and also using processes that automate few steps are of great help in making programs utilize less space and run more efficiently. Programs these days need to run on devices that are smaller and smaller, having code that does not manage memory well can cause major lags in processes which can affect the result that is needed to be obtained.

Learning how to manage memory and run time is a key skill that people look for in a developer.

4.Make It Functional

Every program has a number of independent processes whose results are culminated to produce a final output. Having code written in the form of functional blocks is a way of first de-cluttering the screen making the code more readable, also helps in keeping track of all the separate processes which would enable for more optimized code to be written.

5.No Dead Code

This is a big one to focus on. Many programmers during the development phase comment out a few lines of code,mostly cause they just want to test only one feature at a time. If this commented out code remains in the final version it causes a lot of headaches.

The maintenance team would not really know if the code is required at some point meaning that a question arises about whether the code snippet is necessary or not,hence leading to wasted space and dead code.Leaving dead code is a very amateurish way of programming and strays far away from writing clean code.

In conclusion we see that writing clean code is an essential skill. Many companies look for developers with good programming practices and most times this is what separates the good from the great.

    Useful tips for clean coding. I had done in IT. I love to do coding part instead of designing. And I like the 5th point you said “dead code”. Sometimes coders use to comment out some line of code if that code is not needed or that is not working up to the mark.
