Should I use tabs or spaces for code indentation?
The debate that has divided developers since the dawn of programming. Let AI settle this once and for all. Just kidding, the war never ends.

🏆 Top pick: Use spaces for indentation4.4/5
Go for spaces for indentation—it simply excels in readability. Spaces make the code cleaner and more consistent, which is crucial for maintaining a clear codebase. This option edges out using an IDE/editor setting because it doesn't rely on specific tools and ensures uniformity across different environments. Compared to following team or project standards, it offers a more universally accepted practice that aligns well with personal preferences, making it a versatile choice.
