Other than the IEE-754 he might mean the Wat talk [1] by Gary Bernhardt which is kind of famous for poking fun at JavaScript (and it's unpredictability with things like NaN. As a JS developer myself I find it hilarious.) Though I don't know why it would need to be remade he at least referenced the talk, it seems, with the word Wat, so it's worth mentioning at least I guess
