Ousterhout argues that vague names for variables and methods can lead to confusion and errors. For instance, he critiques the use of generic names like `x` and `y` for variables that could represent anything from coordinates to indices. Instead, he advocates for more descriptive names such as `charIndex` and `lineIndex`, which clearly convey their purpose. This practice not only makes the code more readable but also reduces the likelihood of misuse. Ousterhout emphasizes, 'The code would be clearer if it used names such as charIndex and lineIndex, which reflect the specific abstractions that the code implements.' Consistency in naming conventions is also crucial, as it reduces cognitive load and helps maintain a clean and understandable codebase. | John Ousterhout | A Philosophy of Software Design
