Just a silly question on newlines. Is there a specific reason to put the newline ON the new line, instead of putting the newline on the previous line?

Example from the instructions:

echo “1. [Thing to do]”;
echo “\n2. [Another thing to do]”;
echo “\n3. Learn to have “fun””;

Different example:

echo “1. [Thing to do]\n”;
echo “2. [Another thing to do]\n”;
echo “3. Learn to have “fun””;
