What Hacker News says
3 sourcesDifferential Dataflow is about differential computation which itself is a generalization of incremental computing, most commonly known from Excel.
A good introduction to the overall topic is incremental [0] an OCaml library by Jane Street and the corresponding blog posts and videos [1]. They even use it for webapps [2].

In Differential Dataflowhttps://github.com/leontrolski/leontrolski.github.io/blob/ma... captures the spirit of React.
The "diff & patch" pattern is super common, e.g. Git and Incremental by Jane Street: https://github.com/janestreet/incremental
