How can I pass a string date from a variable to the new Date(...) constructor? The following code produces Invalid Date. Do I need to convert it first somehow?

var dateString = '18/11/2021';
var dateObject = new Date(dateString);
alert(dateObject);

When using the Date(dateString) constructor, the date string must be specified in simplified ISO 8601 date format. Also note that conforming date only formats such as yyyy-mm-dd are treated as UTC, not local. The following should produce the expected result:

alert(new Date("2021-11-18T00:00:00"));

Using any non-standard format is discouraged and the results are implementation specific.

it's your dateString format. First the year, month and then day.

hello = '2021/11/18';
end = new Date(hello);
alert(end);
