Copilot makes refactoring faster and safer — suggest improvements, apply them, then verify nothing broke.

Refactoring Prompts

• "Refactor this to be more readable"
• "Extract this logic into a separate function"
• "Convert this callback code to async/await"
• "Replace this loop with a functional approach (map/filter/reduce)"
• "Apply the single responsibility principle to this class"
• "Reduce code duplication in these functions"

Safety Tip

Always run your tests after applying Copilot refactoring suggestions.
