Seven months ago(2017.3) I start wanted to dig into react src code, but at that time react@16 is still developing and the src code changed very frequently so I have to give it up.
But with the react@16 release formally, I think it's the time to restart this work :)
Currently I just start the work, so the docs are just for back up.
The src directory are used for explore the src code expediently.
Now I will just put the flow chart file or online (choose open in draw.io would be better) to the docs.But if I complete my work, I will try my best to write a artcile(maybe gitbook?) to explain all things in detail.
