Which is the best book for naming variables?
Clean Code: Naming. Best practices for naming variables… | by Shubhashis Roy Dipta | Better Programming Welcome to the first part of the clean code series. This series will be highly inspired by and sometimes embarrassingly copied from the Clean Code book by Robert C. Martin (Uncle Bob). I highly recommend reading the book.
What’s the proper way to name a variable?
There should be enough distinctions in the variable naming. Don’t just append a number if you have a variable with the same name in the scope: a1, a2 is the opposite of intention-revealing. Don’t use names with similar meanings. For instance, product_data and product_info do not have a proper distinction.
Why do we need descriptive names for variables?
If you are having trouble naming your variables, it means you don’t know the model or your code well enough. We write code to solve real-world problems, and we need to understand what our model is trying to capture. Descriptive variable names let you work at a higher level of abstraction than a formula, helping you focus on the problem domain.
