Coding Standards

Correct Answer: Provide her with the project's coding standards documentation and offer guidance on key points

The best solution here is to provide the new member with the project's coding standards documentation and offer guidance on key points. In Agile Scrum, conformity to coding standards is important for maintaining consistency, readability and manageability of the code. As the scrum master, it's part of your role to ensure that every team member is aware of and understands these standards. Telling her to code as she wants would defeat the purpose of coding standards. Similarly, asking her to learn by examining the existing code might not cover all the standards and could be more time-consuming than simply providing the documentation. Lastly, reprimanding her for not knowing the coding standards is an inappropriate response because as a scrum master, your role is to support and facilitate the team's work.

Correct Answer: Descriptive variable names improve code readability and understanding

Descriptive variable names improve code readability and understanding, making the codebase more maintainable. Longer names alone aren't beneficial, job interviews typically have little to do with naming, unique names don't affect memory usage, and relying on comments for understanding is time-consuming. Dismissing the importance of naming ignores the value of clean, readable code.

Correct Answer: Automate code formatting using a linter and formatter

Automating code formatting using a linter and formatter ensures consistent formatting without manual intervention. Manually cleaning code after merges wastes time, disallowing indentation reduces readability, forcing specific editors limits personal preferences, and allowing improper merges or creating separate branches for each style introduces unnecessary complexity.
