The boundary-crossing is definitely the bottleneck right now. We are currently putting alot of work into the Apache Arrow support specifically to avoid this crossover, which will allow us to send data from the server in binary and avoid pa

We use Web Workers principally to separate data CPU load from rendering load, as the datasets we deal with update very frequently and are quite large, and e.g. Highcharts can take on teh order of 100ms+ on detailed charts. We have some ligh

We chose to go with a Web Components based interface for compatibility across frameworks, but alot of where we go in the future will be determined by the expertise of the developers we hire to work on it, and the community if there is inter

We do some benchmarking just for catching performance regressions and validating assumptions against the non-WebAssembly version, but definitely need more in this regard. [benchmark for wasm build]( https://jpmorganchase.github.io

It supports virtualization, and it is utilized by both plugins (Hypergrid and Highcharts). N levels of pivoting on both axes. Should work on all browsers - if not, please open an issue!

We very much plan to continue developing this entirely in the open! It is reputationally important we do not just dump our dead projects on the internet as Open Source, which is one of the reason why we chose Perspective for this project i

Right now, you can call a load() or update() method on an engine or widget to pass JSON, CSV or Apache Arrow data (as an ArrayBuffer) to the engine. Apologize for the documentation clarity - this is our first release and very much under act

The frontend is actually pure JS/HTML - the WebAssembly part is just the data engine, and runs in a WebWorker for CPU isolation. Hypergrid is a canvas-based renderer, yes.

I believe you'd need to port Python to WebAssembly to make much use of pandas - unaware of any projects attempting the former. The grid is just a plugin for the excellent [Hypergrid]( https://github.com/openfin/fin-

True - worth pointing out that this library gracefully falls back to ASM.js if your browser does not support WebAssembly, though.

Not even close to one weekend - I meant "weekend" in the tongue-in-cheek sense that all good weekend hacks spill over into multiple years. [Write yourself a scheme in 48 hours]( http://en.wikibooks.org/wiki/Write_Yourself_a_Scheme_in_48_H..

I think the parameterized modules would be nice, and a natural extension since modules as implemented are technically "first class" - but I'm intentionally shying away from Haskell-level type checking. Ultimately, I'd like the type system

Thanks for the feedback! Forml is an awesome name! Mind if I potentially steal this idea?

er - type inference in ocaml is descendent from ML, which had the feature in the 70s - hell, hindley-milner was published in 1969. This has nothing to do with how recently the language has been developed, it is a simple tradeoff between ty
