Notes on React useRef and Destructuring variables

• You can alias destructured variables

const obj = { x: 1 };

const { x: anotherNameForX } = obj;

• You can use useRef to access previous state values.

const FunctionalComponent ()=>{
const [items, setItems]
const [values, setValues]

const prevState = useRef()

/*
	prevState = {
		items: previousItems
		values: previousValues
	}
*/

}

• JS has internationalization values stored for currencies
  • Intl.getLocaleFormat()
