Why React Hook useState uses const and not let

Question

The standard way to use a React useState Hook is the following:

const [count, setCount] = useState(0);

However this const count

Answer 1

After calling setCount the component is rerendered and the new call of useState returns the new value. The point is that count is immutable. So there's no typo here.

Technically it is a new variable at every render.
