  1. First of all thanks for the very well informed documentation for understanding few very fundamental implementation of JS. Just one question I wanted to put, where you were describing asynchronous behaviour of JS execution I feel you missed one part that before adding to queue tasks assigned to web api’s in case of browser. Please can you also explain that. Also please help me correcting if my understanding is wrong.

  2. OMG, it’s f****ing best ever article on this theme!!! Author, you are crazy! I can’t understand one thing, why it’s not in the official docs of REACT ???!?!?!?!?!?!?!

  3. Great article. Now I’m trying to understand core concepts of the VDOM. It help me much.
    Thank You!

    1. Thanks for catching the typo; it will be fixed shortly. I’ll also add a note regarding the consolidation of the “createFiberFromTypeAndProps” function into “createFiberFromElement.”
