The feedback that you didn’t understand what it was… sorry apparently I failed again… This tool is a live programming environment. The code that you write is organized in cells, and the observable runtime links cells together in a computing graph (similar to how cells in excel form a computation graph). Conceptually it is very similar to data science notebooks (and that is in fact what observable is) The language is JavaScript. Some will say that JavaScript is not suited to do data manipulation, and in many regards it is true. But in many use cases, javascript in the browser is good enough, and it has the added benefit to allow you to use all kinds of data visualization libraries and it doesn’t require you to hire Python guys, which in my experience can bring its own set of problems. What I meant by it being very tactical is that you are limited to calculations that fit in a browser window. So it doesn’t really scale to the size of FB… that said it would allow someone at Facebook to fiddle with the results of some large scale data analysis. Hopefully that explains a little more. But yeah really a demo will be a lot clearer
