Adopt a consistent naming convention

Using a consistent naming convention throughout your codebase makes it easier for others to understand the purpose of variables, functions, and classes. Some popular naming conventions are:

• CamelCase: calculateAverage(), userProfile
• PascalCase: ArrayUtility, PaymentProcessor
• snake_case: user_name, item_price

Choose one convention and stick to it throughout your project.

Use meaningful names

Choose descriptive and meaningful names for variables, functions, and classes. This helps convey the purpose and intention of the code. Avoid names that are too short or ambiguous, like x, y, or temp.
