React state question
Hi,
I've been stuck on this for a few hours now but I can't figure it out.
https://codesandbox.io/s/practical-beaver-vgcmcv?file=/src/App.js
I basically map over an array of items and for each item I made an input to fill in a value of the item.
Filling in a value for this item should do 2 possible things:
Make a new object with the e.target.name, e.target.value and object.amount
or
Update the value in an existing object (if this value has previously been filled in)
