In the world of programming, writing clean codes is the hallmark of a skilled developer. It directly impacts the quality, accountability, and efficiency of your performance. However, many students fail to write concise and expressive codes due to inconsistent formatting and poor documentation.
Therefore, they seek programming help from external agencies who not only assist in writing faster codes but also support in maintaining the readability of your project. According to tech experts, to write readable codes, it is essential to understand the problem that you want to solve.
To expand your knowledge in clear codes, assignment help portals like MyAssigmenthelp.com and similar brands design an inclusive learning session. You can ask programming experts to clarify your doubts and ensure a comprehensive understanding of this field.
In this blog, I have highlighted the key components that developers consider while developing codes efficiently.

5 Tips for Readable and Clean Codes
1. Use Consistent Indentation & Braces
Would you like to read an article if there is no consistency in line spacing, font size, or font style? No right? The same goes for your code. In order to develop an easy-to-read code, make sure indentation (tabs/ spaces), braces, and formatting are consistent.
| Example of A Readable Code: function identifyMagazines (colour) { If (colour !==red) { go_and_identify_the_magazine () ; } else { abort_mission () ; }} |
- You can easily identify from the above code that there is a statement within the function.
- The clear indentation and braces make it easy to understand the starting point and finishing point of the code blocks.
- See how opening braces for the and are in the same position.
| Example of A Bad Code: function identifyMagazines (colour) { If (colour !==red) { go_and_identify_the_magazine () ;} else { abort_mission () ; } } |
- You can’t say where the function ends and where the block starts.
- The braces are all over the place, and one can’t understand the opening and closing braces easily.
- The line spacing is also inconsistent. Look how is written.
2. Use Clear Variable and Names
Many junior developers and students make a common mistake- choosing the correct names for their codes. If the functions are named accurately, readers can easily visualise the codes.
| Example of Good Naming in Code: function changeMagazineLable1Text (Magazine Colour) { const magazineNameLable1 = identifyMagazineName(magazineColour):}function getMagazineName (MagazineCode) { const magazine = api.identifyMagazineByColour (magazineColour) ; Return magazine.colour;} |
- This function is written clearly by naming each variable properly.
- Readers will easily understand that if they apply the method with a , they will get a magazine name back.
- It is also easy to see the method called , used for intilising the variable magazine.
- Similarly, readers can easily analyse from the above function that identifies a magazine and returns the colour property.
3. Use Only Three Parameters
Always remember that it is convenient to understand upto three parameters at a time. But, if you use more than three parameters in a function, readers will get confused.
| Example of Unclear Parameters In Coding: function createinterview (intervieweeName, hrName, date, time, venue) {} Example of Clear Parameters In Coding: function createinterview (intervieweeName) {} |
- The first example is quite confusing as readers won’t be able to understand what you are trying to find out.
- If you see the second example, it is easy to decipher that if you call , the interview name will return.
4. Try to Solve One Problem
Students are so much in a hurry that they try to solve multiple problems with one function. If you also do the same, stop immediately! To avoid redundancy in coding, you must develop short and easy functions rather than complex programming.
| Example of Complex and Confusing Code: function createinterview (interview) { const date = interview.date const intervieweeList = getIntervieweeList () const currentInterviewee = intervieweeList.find (interviewee => { interviewee.name = interview.interviewee.name}) const currentHr = hrList.find (hr => { hr.name = interview.hr.name})sendToCreateInterview (currentInterviewee, currentHr)} |
- Here, the developer tries to solve three problems at a time: interviewee names, data, and Hr.
- Readers may get confused by this, and it will take hours to read and understand each function properly.
| Example of Easy and Clear Code: function createintervieweeList (interviewee Name) { const interviewee= intervieweeList.find(interviewee => { intervieweeName = interviewee.name }) Return (interviewee)} |
- From the above function, a reader can easily understand that the function contains only one problem, which is .
5. Create a Descriptive Message
While creating a commit, make sure to write a descriptive message so that one can understand the intention of your code. To do this efficiently, you need to avoid vague descriptions. For example, if you write a one-word message like refactoring, it may not be clear enough for others.
| ❌ tomgracias@Evans-MacBook-Pro ~%git commit -m “refactoring” ✔️ tomgracias@Evans-MacBook-Pro ~%git commit -m “Get interview data from HRIS” |
Apart from that, you can use popular style guides like PEP 8 (Python code), Ruby (Ruby developers), Airbnb (Java developers) to maintain consistency and, readability, and conventions.
Bottom Line
Whether you are working independently or in a group, these suggestions will help you toward creating efficient code that is of the highest quality. So, apply these tips in your next coding project and see the results.
Enjoy Coding!
