Isn't that just semantics? Whatever name you give the feature "lazily computed and cached values in the context of web frameworks", previously Angular didn't have them (built in) and now they do.
Are you aware what comment tree you are in? This whole thing started because GP wrote this:
> For example, this update brings us computed properties, an essential feature for any complex performant web application that was made popular by Vue.js 10 years ago [1].
So obviously the relevant definition is "what the feature does in Vue". What is your issue here?
