Component will mount/component did mount is effectively construction. Component will unmount is effectively destruction. Apparently them changing the names makes you believe thats not what it is Polymorphism and inheritance can be implemented if you wanted. Mixins were used for a while. Xml is react native and all other alternative rendering that use jsx syntax and a form of react React alternatives where you create/destroy/append/prepend would be the DOM. Patching is interesting in that the inline html isnt actually html until the end of the render loop. I dont remember seeing that anywhere else to be honest. It seems more similar to transforms like in node streams.
