I was working with React Projects for a long time. I have evolved a mindset that allows you to abuse HOC to make code more reusable and somewhat clean. But when I got into Angular, it felt weird at first that there is no such concept.
The Spark
At some point, I got in touch with Modals and there it was the gong that awoke the ninja in me. First, I dove again into angular.io docs and indeed found a way to pass components through @Input() and render them. But that was unsatisfying because of the directive. That could be because decorators are something new after React. Or because it splits such a simple concept as HOC into too many files.
