setYear(year => year + 1)

For the "get off my lawn" crew:

    $('#year').text(Number($('#year').text()) + 1)

don’t start the year by mutating state, geeeeeez :)

It's not mutating state, it's defining a transition function from one immutable state to another!

[year, setYear] = useState(2024)

Get off my lawn means no libraries, just web api.

year = year + 1
