javascript date comparison

Some interesting things about client-side javascript date comparison - 

• if you want to compare with ==, you would need to prefix the variable with a + but > and < would work fine.
  
  
• you can't just write
  if ( Date(datestring) < Date("2022-12-08 23:59:59" ) ) - you need to create new Date(string) explicitly, like
  var d1 = new Date("2022-12-07 23:59:59" );
  var d2 = new Date("2022-12-08 23:59:59" );
  var testdate = new Date(testdatestr);
  if ( testdate > d1 && testdate < d2 )
