Why are you replying to yourself?

And what does the use of " (double quotes) versus ' (single quotes) have to do with the question being asked in this thread? Which one of us is confused? ;)

Update: Oh, I get it. You're still of the mistaken notion that contributing a lot of posts (even if they're total rubbish) is going to somehow help you to "win the game."

By the way, the choice between single and double quotes should have nothing to do with shaving clock cycles. Whoever says, ""OMG don't use \' unless you relay need to." is just being hysterical. Use the operator that conveys the semantics most appropriate to your code's needs. If you need interpolation, use double quotes. If you don't need interpolation, use single quotes, because then when you read the code you know right away, "there's no interpolation going on here." And when you need to embed quotes, use an alternate quote-like construct. Code for clarity.
