Calculator App

That is a nice attempt on the challenge, however there are lot of issues in your code and the app, have you noticed that you some operation return . Try 5 X 3/2 as an example secondly if i type a period, a normal calculator shouldn't allow to type another one, you should implement that functionallity in your app. I noticed you have used the eval function which is discouraged for security reasons. These and many other issues, overall i would encourage you redo this project and give it all you can.

To properly center the component in the page, you should use Flexbox or Grid layout. You can read more about centering in CSS here 📚.
