How can I add 1 day to current date?

Question

I have a current Date object that needs to be incremented by one day using the JavaScript Date object. I have the following code in place:

var ds = stringFor

Inspired by jpmottin in this question, here's the one line code:

var dateStr = '2019-01-01';
var days = 1;

var result = new Date(new Date(dateStr).setDate(new Date(dateStr).getDate() + days));

document.write('Date: ', result); // Wed Jan 02 2019 09:00:00 GMT+0900 (Japan Standard Time)
document.write('
');
document.write('Trimmed Date: ', result.toISOString().substr(0, 10)); // 2019-01-02

Hope this helps
