REACT TS roperty 'value' does not exist on type 'EventTarget & Element'

@Zyon Lyod has already provided the code and some explanation but i will add
more details:
The problem is that not all html events have the value property. And thus not all
event.target have that property since event.target is a generic html element
so you need to cast to the html element that you are using
You are welcome,

// If you have to use event.target itself, you would have to cast the object:

const { name } = event.target as HTMLButtonElement;
