Referencing constants by name instead of values enhances code readability and maintainability. When constants are represented by meaningful names, they provide context to the values they represent, making it easier for anyone reading the code to understand what these values signify in real-world terms. This practice avoids the confusion of encountering raw numeric values, which may not be immediately clear or could be misinterpreted.

Using descriptive names for constants also aids in ensuring consistency throughout the code. If a constant needs to be adjusted, changing its value in one place updates all instances where the constant is referenced. This reduces the risk of errors that can occur when numeric values are hard-coded and repeated across the program, thereby promoting better coding practices.

While using numeric values directly, minimizing the number of constants, and limiting variable use might sound practical in some scenarios, these approaches generally do not ensure clarity or maintainability in the long run. Naming constants meaningfully provides clarity and context, making it a more robust practice in programming and engineering contexts.
