Data Driven UIs, Incrementally

on YouTube ↗36m

" summary

Claims that an OCaml library called Incremental (OCaml) records dependency graphs to update only affected computations, and that the same code runs server-side and compiles to JavaScript to drive DOM updates. Implements symmetric diffs over persistent maps, plus split/join primitives and an inker_map that streams per-key incrementals, enabling responsive tables of 100,000 rows that stay zippy. Shows diff and patch as the practical bridge between functional data structures and efficient incremental UIs.
