React to do app problem was a sandbox with a live application that had an incomplete To-Do app and you had to go in and find out what was missing and fill it in the right places. There is a bunch of Typescript in the code as well which threw me off, but don't be alarmed and just try to focus on what you know. Find the function for the To-Do app and then connect it to the component on the right file to make it work. It's a basic to-do app and shouldn't be hard if you can just focus on the React and do it quickly because it takes a minute to figure out the different components and where everything is. Then you have to actually start coding, so time is not your friend lol.
