The tutorial has issues with the sound as without earphones its barely audible can understand the author has low voice but volumes could have been increased. As its not possible to wear earphones all the time it was difficult. The thing i liked about the course is that its precise to point and gives good insight of code demos and helps to understand concepts still i had to upgrade to the latest versions and using of libraries for better adaption of current coding. I totally enjoyed learning new concepts definitely recommended to leverage React JS. Thank you !

This course is a great introduction to React Js. Rayan patiently takes us through the journey, explaining the various concepts clearly at every stage. He even goes the extra mile to explain code related to technologies that are not the focus of the course such as ES6 and CSS. With the concepts explained well, I was able to integrate with newer versions of redux and firebase without much difficulty.

It was really helpful thanks

By Jeff Kehler on 11/14/2020

I honestly likes the content and approach of this tutorial. The instructor did a decent job of explaining things for the most part. Could have gone a bit slower in some spots, especially towards the end when the code become more complex. My biggest issue is that this course being a few years old does not seem to get any attention from the instructor. There seems to be a common error: TypeError: this.props.startLoadingPost[all of the action functions] is not a function. In the end I could not run the application being build. Many hours were wasted trying to resolve this to no avail. From the comments in the Q&A section I'm not alone. If the course is still being sold it should be updated and supported.
