I know Python+Jupyter. I'm also a user of Julia+Juno.

What does Pluto give me that Juno doesn't? Pluto is called a "notebook" - in what ways is Pluto like Jupyter, in what ways is Pluto like Juno, and in what ways is it unique?

Here [1] I see sliders. Wouldn't it make more sense to integrate the sliders into Juno than writing a whole new IDE just so you can use sliders? Other than sliders, how else is it unique?

UPDATE: I just spent 5 minutes on it and I see that it's reactive. That's neat. But I'd still prefer to have this as an add-on to my IDE than on the browser.

UPDATE2: Oh and reactive plots too. Neat.

UPDATE£: Oh and I can really easily export to html..
