What is the primary problem with large, multi-purpose functions according to software development best practices?
They execute too slowly and consume excessive memory.
They violate the Single Responsibility Principle and are difficult to read, maintain, and test.
They require more advanced programming languages to implement properly.
What is a common threshold guideline for considering a function too large and in need of refactoring?
Functions with more than 10 lines of code.
Functions with 40-50 lines of code or more should be scrutinized for refactoring opportunities.
Only functions with more than 200 lines need to be refactored.
Which of the following answer choices is a key indicator that a function violates the Single Responsibility Principle?
The function returns a complex data type.
The function contains multiple levels of nested loops and conditional statements.
The function contains commented sections like '// Step 1', '// Step 2' that suggest multiple distinct responsibilities.
What is cyclomatic complexity and why is it important for identifying large functions?
It measures the physical lines of code in a function.
It measures the number of independent paths through a function's code, with higher values indicating more complex logic that's harder to test.
It measures how many times a function is called throughout the application.
When using GitHub Copilot's Ask mode to analyze large functions, what is the most effective approach?
Ask generic questions like 'Is this code good?' without providing specific context.
Ask specific, targeted questions like 'Can you summarize what this function does?' and 'List the distinct tasks this function performs.'
Only ask about syntax errors and code formatting issues.
What is the primary advantage of using GitHub Copilot's Agent mode for refactoring large functions?
It automatically identifies all bugs in the original function.
It can autonomously analyze, plan, and implement refactoring tasks while allowing you to review and approve changes.
It eliminates the need for any testing after refactoring is complete.
What should you do immediately after extracting a method from a large function during refactoring?
Continue extracting the next method without testing the current extraction.
Test the extracted method to verify that functionality remains intact before proceeding to the next refactoring step.
Wait until all extractions are complete before running any tests.
When using GitHub Copilot Agent mode to refactor large functions, what is the most effective strategy?
Ask GitHub Copilot to refactor the entire function in a single command to save time.
Break the refactoring into small, specific steps and review each change carefully before proceeding.
Let the agent make all decisions without any human review or intervention.
You must answer all questions before checking your work.
