Clean Code Guidelines

1. Code Readability and Structure

• Descriptive Naming: Use variable, function, and class names that reveal intent. Avoid confusing abbreviations or meaningless names (e.g., use activeUserCount instead of auc).
• Focused Functions (Do One Thing): Each function/method should perform exactly one task. Ideal functions are short (under 20 lines) and maintain a consistent level of abstraction.
• Minimize Parameters: Limit the number of function arguments. Ideally 0-2 parameters. If a function requires 3 or more arguments, wrap them in a configuration object/struct.
• Avoid Side Effects: Ensure functions do not mutate external state unexpectedly. Favor pure functions where possible.
