Have you ever used React before for the JavaScript library?
No I haven't, but I've heard about it. It is used by both Facebook and Instagram.
It is good to use by beginners isn't it?
It can be. It really helps to increase speed. It's pretty simple and also aids in scalability.
I see that a big advantage is that it is easy to debug.
Perhaps you can contact Jordan Walke for more information, since he is the creator of it.
