Practical React Programming

So far, many people have requested practice code.
I couldn't provide it to you quickly because I was busyㅜㅜ

Now, finally, you can check out almost all the code used in the lectures in an online IDE (CodeSandbox)!
Please refer to the links at the bottom of each lecture screen.
I expect it will be a great help in learning since you can check the results while directly modifying the code online.
