When to use \" vs. '

"hi!"        # No quotes in the string, use double quotes

"hi!"

'I said "hi!"'         # Doubles quotes in the string, 
                       # use single quotes

"I said \"hi!\""

"I'd say \"hi!\""         # Doubles and single quotes in the string, 
                          # use double quotes

"I'd say \"hi!\""
