You speak with authority, but with ignorance. MS had a lot of JavaScript and needed to put some semblance to the madness of development. Read early history. Watch some talks of Hejlsberg, they are insightful and makes you a better developer.
Cool, great if you could slow down the animation so we can understand what each action means.
(It's hard to see this from your side as you've seen this perhaps hundreds of times)
Xpath’s relationship to XML is like CSS to HTML: its natural domain—and most common use—is XML. However, it is a general path selection/query mechanism with a UNIX-file-path-like syntax.
There are large parts of XPath which are XML specific, like attributes or namespaces or node names (JSON’s arrays of arrays have neither). I am sure with enough effort one could use Xpath for generic JSON queries, but this will require non-obvious redesign of the language.
This is not about buying or renting, it's about an alternative to Spreadsheet for model building. But not much info on the process itself.. can creators expand on this.
Haha yes — glad that came across :) It's still very early days for the product, but the basic "building block" for models will be these nodes that you see on the demo. They can be fixed constants, inputs, functions of other nodes, etc. You can create these nodes and define how they related to one-another — this is the "model". Then you can decide what kind of outputs you care about and how you want to show them.
Probably sounds quite abstract! If you leave your email on the site then I'll drop you a line as soon as we're ready to show the product :)
