Yeah, a while ago I discovered this slick JS notebook app called Tonic, and could never remember the name until one day I came across this thing called RunKit and I thought that it must be a clone. Nope, name just changed when Striped acquired it. When I saw this app, I thought Tonic must have gone through another rebranding. Wrong again! This just looks more geared for data visualization and collaboration though. Would be curious to see if Tonic/RunKit (or iPython even) were used as inspiration.
