A resource for learning JS?

Question

JavaScript

Please tell me - there is such a site - a guide to JS. I managed to lose it unfortunately. There is exactly the key information on JS, a completely black background, and the sidebar with navigation seems to be on the right. Information goes sequentially if you scroll down. Maybe someone understands well what I mean - please throw off the link, I will be very grateful.
