Angular certainly didn't kill ExtJS. I was on a project that tried to move from Ext to Angular 1. UI-grid alone forced us to stay with Ext. Add in all the other Ext components and moving to Angular along with re-creating everything simply didn't make financial sense. For what it's worth, I think they later re-wrote in React and integrated the Ext grid in that.
