  1. S

    S.js - Simple, Clean, Fast Reactive Programming in Javascript (by adamhaile)

    This article never mentions React. This has nothing to do with React. There's a reason people say "react is not reactive"[1].

    Signals are derived from Observables[2] which were first used in Adam Haile's S.JS[2] and made popular in JavaScriptLand by Ryan Carniato's SolidJS[3].

  4. datastar

    The hypermedia framework.

    There's also Datastar that uses signals and ends up being the best of HTMX and Alpine.js combined (at a smaller bundle size too).

  5. materialize

    Real-time Data Integration and Transformation: use SQL to transform, deliver, and act on fast-changing data. (by MaterializeInc)

    This triggered some associations for me.

    Strongest was Cells[0], a library for Common Lisp CLOS. The earliest reference I can find is 2002[1], making it over 20 years old.

    Second is incremental view maintenance systems like Feldera[2] or Materialize[3]. These use sophisticated theories (z-sets and differential dataflow) to apply efficient updates over sets of data, which generalizes the case of single variables.

    The third thing I'm reminded of is Modelica[4], a language where variables are connected by relations (in the mathematical sense). So A = B + C can update on demand and, as well, you can update just A and B, then find out what C must have become.
