Here are the five things you can use to increase your code quality
๐ญ. ๐๐ผ๐ผ๐ฑ ๐ป๐ฎ๐บ๐ถ๐ป๐ด
Choose clear, descriptive names for variables, functions, and classes. Good naming reduces the need for comments and makes the code self-explanatory.
๐๐
๐ฎ๐บ๐ฝ๐น๐ฒ: Don't use ๐๐๐๐๐๐๐() for a function with an unclear purpose or data or x for variables with ambiguous meanings. Use ๐ฒ๐๐๐๐๐๐๐๐๐ผ๐๐๐๐๐๐ข๐๐๐๐๐๐๐() for a function that computes monthly revenue.
๐ฎ. ๐ฆ๐บ๐ฎ๐น๐น ๐๐๐ป๐ฐ๐๐ถ๐ผ๐ป๐
Write functions that do one thing well (Single Responsibility Principle). This approach leads to more testable and reusable code, enhancing simplicity and efficiency.
๐๐
๐ฎ๐บ๐ฝ๐น๐ฒ: Instead of ๐๐๐๐๐๐๐๐๐๐๐(๐๐๐๐๐), which finds a user by email, sends a welcome email, and logs activity all in one function, use ๐๐๐๐๐๐๐๐๐ฑ๐ข๐ด๐๐๐๐(๐๐๐๐๐), which considers only a user by email.
๐ฏ. ๐๐ผ๐ฑ๐ฒ ๐ ๐ผ๐ฑ๐๐น๐ฎ๐ฟ๐ถ๐๐
Organize code into well-defined, loosely coupled modules. Modular code is easier to manage, test, and debug and supports scalability.
๐๐
๐ฎ๐บ๐ฝ๐น๐ฒ: Instead of a single ๐๐๐๐๐ผ๐๐๐๐๐๐๐๐๐ module that handles authentication, profile management, and user settings, create a ๐๐๐๐๐ฐ๐๐๐๐๐๐๐๐๐๐๐๐๐ module that handles login and registration, while a separate ๐๐๐๐๐ฟ๐๐๐๐๐๐ module manages user profiles and preferences.
๐ฐ. ๐๐ผ๐ป'๐ ๐ฆ๐๐ฟ๐ฝ๐ฟ๐ถ๐๐ฒ
Write code that behaves in a way users and other programmers expect. This principle reduces cognitive load, making your code more intuitive and easier to work with. It's about aligning with human expectations, not just computer logic.
๐๐
๐ฎ๐บ๐ฝ๐น๐ฒ: Don't create a function named ๐๐๐๐๐๐๐๐(), which, apart from saving user data, also sends an email to the user. This function should save the user.
๐ฑ. ๐๐๐ผ๐ถ๐ฑ ๐ฐ๐ผ๐ฑ๐ฒ ๐ฑ๐๐ฝ๐น๐ถ๐ฐ๐ฎ๐๐ถ๐ผ๐ป
If you find yourself writing the same code more than once, consider abstracting it into a function or a module. This reduces the codebase size, minimizes potential bugs, and simplifies maintenance.
๐๐
๐ฎ๐บ๐ฝ๐น๐ฒ: Suppose you want to format user input in a specific way instead of writing this logic every time you need to format user input. In that case, you create a single function, ๐๐๐๐๐๐๐๐๐๐๐ธ๐๐๐๐(), and call this function wherever the formatting is required.
And remember that a good code is like a joke, you don't need to explain it.
