1 Choose meaningful names

One of the most important aspects of writing understandable code is choosing meaningful names for your variables, functions, classes, and modules. Names should convey the purpose, role, and scope of your code elements, and avoid ambiguity, confusion, or misleading information. For example, instead of using names like x, y, or z, use names like price, quantity, or total. Instead of using names like do_something or foo, use names like calculate_average or generate_report. Use consistent naming conventions and follow the style guide of your programming language.

Yes writing meaningful names is most important. Like uploadToS3Bucket means it is a helper function to uploading data to S3 bucket. Likewise alot of things is understood from these functions.

2 Write comments and documentation

Another way to make your code more understandable is to write comments and documentation that explain the logic, functionality, and expected behavior of your code. Comments should be concise, accurate, and relevant, and avoid stating the obvious or repeating the code. Documentation should provide an overview of your code structure, design, and dependencies, and include examples, tests, and references. Use tools and formats that make your comments and documentation easy to read and maintain, such as docstrings, Markdown, or Javadoc.

Writing comment in code with TODOS helps us in remembering code and helps other developers understand the code. They can easily modify and reuse code if two developers understands each other code.

3 Follow coding standards and best practices

Coding standards and best practices are guidelines and principles that help you write code that is consistent, reliable, and maintainable. They cover aspects such as indentation, spacing, formatting, syntax, naming, structure, modularity, reusability, and error handling. Following coding standards and best practices not only makes your code more understandable, but also more compatible and interoperable with other code. You can use tools and frameworks that enforce coding standards and best practices, such as PEP 8 for Python, ESLint for JavaScript, or RuboCop for Ruby.

4 Use clear and simple logic

The logic of your code is the core of its functionality and behavior. You want your logic to be clear and simple, so that other developers can easily follow and modify it. To achieve this, you should avoid unnecessary complexity, redundancy, or obscurity in your code. Use simple and expressive expressions, statements, and operators, and avoid nested or long conditions, loops, or functions. Break down your logic into smaller and modular units that have a single responsibility and a clear input and output. Use comments and documentation to explain the logic of your code.

5 Test and debug your code

Testing and debugging your code is essential to ensure its correctness, performance, and quality. It also helps you identify and fix any errors, bugs, or vulnerabilities that could affect the understanding or functionality of your code. You should test and debug your code at different levels and stages of your development process, using tools and methods such as unit testing, integration testing, regression testing, debugging tools, logging, or exception handling. You should also document and communicate your testing and debugging results and actions to other developers.

6 Seek and provide feedback

One of the best ways to improve your code readability and understandability is to seek and provide feedback from other developers. Feedback can help you spot and correct any issues, mistakes, or inconsistencies in your code, and learn from other perspectives, experiences, and best practices. You can seek and provide feedback through various channels and formats, such as code reviews, peer programming, online forums, or mentoring. You should be open, respectful, and constructive when giving and receiving feedback, and use it to enhance your code quality and skills.

Don't try to write clever statements all in one line, always consider readability. Although tempting to think of one line as more performant it's not necessarily true so keep it simple
