UIs are streaming DAGs

hyperfiddle/photon: a streaming Clojure dialect specialized for full-stck UI

Ideas
We would want to create UIs where we can just declare what data to pull from UIs and not care about.
This can be done by defining UIs as a DAG of operations and data.
This interfaces should be reactive, like in ReacJS.
To do this, the data should be streamed.
For this to work it should run natiley async.
This ideas are implemented on a Clojure dialect: photon
In photon, both the client and the server run their DAG in parallel.
Each one gets as far as it can with the data they have and then wait.
The server predicts what the client will need, and streams it without being asked.
Client inputs are bound to a variable that the seer can access.
It can build the DAGs through functions and lambdas
They explain how they do it, as a operation they call `splice`
Described as a
monadic join operation
They call the DAG a
self-adjusting computation
