Ask HN: Why are entity component systems not used widely in web development?

Entity component systems https://en.m.wikipedia.org/wiki/Entity–component–system are used in game development, and claim great benefit in simplifying codebases.

A cursory glance around doesn’t show any web front end libraries based on ECS.

Why have they not had more impact in web front end application development?
