Use Meaningful Variable and Function Names
Follow the Single Responsibility Principle
The Single Responsibility Principle states that “every module, class, or function should have one, and only one, responsibility.” Following this principle will help you write code that is easier to read, debug, and maintain. This means that each function or module should have a clearly defined purpose, and should only perform tasks related to that purpose.
Use Modular Code
Use Proper Syntax
Use Comments and Documentation
Comments and documentation can help make your code easier to understand and maintain. Use comments to explain complex sections of code, and add documentation to describe the purpose and usage of your code. This will make it easier for other developers to read and understand your code.
Use Code Formatting and Linting
Code formatting and linting can help make your code easier to read and maintain. Code formatting tools like Prettier can automatically format your code according to a consistent style, making it easier to read. Linting tools like ESLint can help identify potential errors and issues in your code, and can be used to enforce code quality standards.
Avoid Global Variables
Global variables can make your code difficult to read and maintain. They can cause unexpected behavior and can make it difficult to track down bugs. Whenever possible, avoid using global variables and instead opt for local variables that are scoped to a specific function or module.
Test Your Code
Testing your code is a great way to ensure that it is working correctly and is maintainable. Writing tests can help you identify potential errors and bugs, and can also help you refactor and improve your code. Testing can also make it easier to add new features without introducing new bugs.
Keep Your Code DRY
The DRY (Don’t Repeat Yourself) principle states that “every piece of knowledge should have a single, unambiguous, authoritative representation within a system.” Following this principle can help you write code that is more maintainable and easier to read. Try to avoid repeating code, and instead opt for code that is modular and reusable.
