Question

A developer is maintaining a pricing module where literal values like 0.0825, 100, and 1.5 appear repeatedly across several calculation functions. Reviewers keep asking what each number means. The developer selects the module and asks Copilot Chat to help improve maintainability. Which Copilot-assisted refactoring approach best addresses the reviewers' concern while preserving behavior?

Accepted Answer

Ask Copilot to extract the repeated literals into well-named constants (e.g., SALES_TAX_RATE) and replace all usages, then verify the existing tests still pass.

Answer

Ask Copilot to inline every function into a single large method so the numbers appear only once in the whole file.

Answer

Ask Copilot to add a comment next to each literal explaining its meaning without changing any code.

Answer

Ask Copilot to convert all the numeric literals to strings so they are easier to search for in the codebase.
