💡 Frequently Asked Questions
Q: Does formatting change the execution of JavaScript?
A: No. JavaScript ignores whitespace and line endings outside of string literals. Formatting only inserts clean line returns and indentation columns to make nested logic clear for humans, preserving programmatic functionality.
