"New props" arrow label is misleading about react-lifecycle-methods-diagram

[csr632]

Agreed. "New props" is confusing and doesn't have any (correct) meaning. "Parent rerenders" give infomation about "why" and "when", just like the "set­State()" and "force­Update()" labels do.

Thanks for your input @csr632 ! In the meantime, I've had a colleague suggest "nextProps". Also, maybe "parent render()" would be preferable to "parent rerenders" to clarify the possible ambiguity between the React lifecycle render() method vs. the browser rendering. Not sure if Dan has any opinion about this...

I feel that "parent render()" is perfect.

When I give a course, I use this wording:
Render: the method to generate the virtual DOM. (generates a tree structure of React Elements, which are simple js objects).
Reconcilation: the React process to update the DOM. (React does this by comparing the current vDOM with the previous one.)
Browser paint or Browser refresh: the browser process to show the DOM on the screen.

Totally agreed! This arrow is very misleading, which confused me for quite a long time...for correctness, as long as parent component rerenders, child components should rerender as well (not if its shouldComponentUpdate returns false)
