Review for React Data Visualization — Build a Cryptocurrency Dashboard

Score: 4/5

I really learn a lot from this course!
the feature div.css is very new to me!
I used to using bootstrap, in the future, I will consider to use that.

I learn localStorage technique a lot from this course!
actually I only used localStorage before when I need to login. Others, I just pass props or Redux to do that.

The instructor has a strong JS skill!

there are some down sides.
The unclear code
I think it will be better to just focus on Edit, not to use editor and chrome at the same time. the screen is already small.

The code structure is not cool
Even the final version, the code is not well-readable. I will prefer to use more component to do that and helper function.
There are too many function in one file(App.js)
Even I completed this course, I will take some time to refactor them with more concise structure I feel comfortable.

PS:
The course is not fit the new engineer with JS or React.
This course is not easy learn, I just want to say if you are the beginner in JS but you will learn a lot you put much time to do research that.
