Since DB is not implemented in this task, the initial state of mock orders comes from: server/db/mock-orders-obj.js Note:

• The state is reset to default only when server restart
• JS file is used for easiness of manipulation
• All operations are async, to simulate requests to DB

1. FrontEnd: If order is confirmed with the same amount as previous one (and amount is 1 character: between 1-9), then [buy] and [sell] buttons are disabled until you blur any other element It seems to be a bug of react-hook-form library
2. FrontEnd: findDOMNode is deprecated in StrictMode - error is thrown in console when snackbar is opened It a bug of react-simple-snackbar library itself
3. BackEnd: Order amount is not taken into account when closing matching buy<=>sell orders: It means that order can't be filled partially - the system will ignore differences in sizes
