Which one is easier to read? I hope you say the one on the bottom. When debugging code, having some type of formatted code (using indents, spaces, etc.) makes debugging much easier because the page is easier to read. Think about the first code sample above if it were a much larger application. Even if you have an editor that shows each line and an error shows the exact line..having formatted text still makes it much easier to debug.
Excellent point!!!
