If you haven’t worked with JavaScript in the last few years, these three points should give you enough knowledge to feel comfortable reading the React documentation:

• We define variables with let and const statements. For the purposes of the React documentation, you can consider them equivalent to var.
• We use the class keyword to define JavaScript classes. There are two things worth remembering about them. Firstly, unlike with objects, you don't need to put commas between class method definitions. Secondly, unlike many other languages with classes, in JavaScript the value of this in a method [depends on how it is called](https://developer.mozilla.org/en-US/docs/Web/Jav

This was nice and fast... but it takes up WAY TOO MUCH space. And it's annoying to write.
(I like the way I can just step into the function that calls the delegate for debugging)

What's a better way to not make me call respondsToSelector in the middle of my code? Some proxy?

    struct {
        unsigned int delegateWillDisplayDocument:1;
        unsigned int delegateDidDisplayDocument:1;
        unsigned int delegateDidShowPageView:1;
        unsigned int delegateDidRenderPageView:1;
