Javascript Date: next month

Question

I\'ve been using Javascript\'s Date for a project, but noticed today that my code that previously worked is no longer working correctly. Instead of producing Feb as expected

Answer 1

ah, the beauty of ternaries:

const now = new Date();
const expiry = now.getMonth() == 11 ? new Date(now.getFullYear()+1, 0 , 1) : new Date(now.getFullYear(), now.getMonth() + 1, 1);

just a simpler version of the solution provided by @paxdiablo and @Tom

Answer 2

try this:

var a = screen.Data.getFullYear();
var m = screen.Data.getMonth();
var d = screen.Data.getDate();

m = m + 1;
screen.Data = new Date(a, m, d);

if (screen.Data.getDate() != d)
screen.Data = new Date(a, m + 1, 0);
