In fact it is probably all Javascript. The formula editor at the top is an Ace editor, the spreadsheet itself is based on https://github.com/openfin/fin-hypergrid, which is an incredibly enourmous piece of software I had never heard of and which I don't understand at all what it is trying to accomplish, but I can see it renders to canvas.

CEO of AlphaSheets here! Javascript is our frontend, but the backend is Haskell :)

So the computations are server-side? Or are you doing some Haskell-to-JS-transpiling?

Yes, the computations are all done server-side, which lets us parallelize big computations. It also keeps our thorny evaluation logic crisp and maintainable, because Haskell. =)

what's your opinion on various spreadsheet like JS frameworks like Handsontable, Crossfilter, NxSheet and fin-hypergrid ?

As someone who has built an internal dashboard using Handsontable, I am yet to find a truly reactive JS framework for spreadsheets.

We're actually built on top of fin-hypergrid, which we chose for its speed. We're handling all the reactivity in the backend.

What do you mean by "truly reactive" in this case?

Formulas that get recomputed if the cells are relevant. A spreadsheet is inherently reactive.
