Question

You maintain a Node.js service where a large module uses nested callback-style functions with manual error propagation. You want GitHub Copilot Chat to help modernize this code to use async/await while keeping behavior identical. Which approach gives you the most reliable modernization result?

Accepted Answer

Select the callback-based function, use Copilot Chat to request conversion to async/await, then review the diff and run the existing test suite to confirm behavior is preserved

Answer

Ask Copilot Chat to rewrite the entire module at once without selecting any code, then commit the result directly since Copilot preserves semantics automatically

Answer

Rely on Copilot inline completions to gradually replace callbacks as you type, trusting that suggestions are validated against runtime behavior

Answer

Ask Copilot to delete the legacy tests first so they don't conflict with the new async patterns, then regenerate everything from scratch
