Would love to see an insiders view on what killed angularjs. Technically there were limitations with that approach but by that point that had such marketshare. Did they consider that everyone would flee or did they feel like the developers would just be pulled along?
As far as I've seen, what killed it was the issue that Angular "v2" was so different from Angular.js (v1) that the upgrade path simply wasn't there. Eventually an upgrade path emerged where a page ran both a bulky Angular.js app AND an Angular v2 app, but it wasn't good enough. By then, React (and to a lesser extent Vue) were looking far more interesting so many teams made the decision that if they had to rewrite their app, they may as well write it in something that has a large community around it and was seen as the "latest and greatest".
It's a shame as I liked a lot of Angular.js but it still lags behind in size and performance these days so it's only attractive to teams that know they're making large, heavyweight web-based software from the start.
