Common in: JavaScript, Java, Swift, TypeScript
Format: First word in lowercase, subsequent words are capitalized.
Example: orderStatus, customerName, totalPrice

Common in: C#, .NET, TypeScript (for classes, enums)
Format: Each word starts with an uppercase letter, including the first word.
Example: OrderStatus, CustomerName, TotalPrice

Common in: Python, Ruby, PHP, C
Format: Words are lowercase and separated by underscores.
Example: order_status, customer_name, total_price

Common in: URLs, some configurations, CSS class names
Format: Words are lowercase and separated by hyphens.
Example: order-status, customer-name, total-price

Common in: Constants, environment variables (in many languages like Python, C, Go)

Format: Variable names are prefixed with letters representing the variable type.

Descriptive & Meaningful: Variables should represent their purpose. For example, instead of using x, use productPrice or orderCount.
Avoid Single Letters: Except for loop counters (e.g., i, j), avoid single-letter variable names.
Use Consistent Conventions: Choose one naming convention (like camelCase or snake_case) and use it consistently across the codebase.
Avoid Abbreviations: Unless they're well-known, avoid abbreviations that can confuse others reading the code.
