How to convert dates correctly?

Question

JavaScript

Hello.
I have a dynamic string like:

const dateString = `${formattedCurrentDate} ${timeSlot?.startTime}`; -> `2021-10-21 13:30`

I run it through new Date() In the browser, everything works fine, but I do it on the backend, and it jumps to the console
const currentTimeSlotDate = new Date(dateString);

console.log(currentTimeSlotDate); -> 2021-10-21T13:30:00.000Z

If we go to the browser and enter , we will be givenconsole.log(new Date("2021-10-21T13:30:00.000Z"))

Thu Oct 21 2021 16:30:00 GMT+0300 (Eastern European Summer Time)

And you need

Thu Oct 21 2021 13:30:00 GMT+0300 (Eastern European Summer Time)

Answer 1

Date.toString()

Answer 2

More correctly:
int a = (editText1.getText() == null)?0:Integer.parseInt(editText1.getText().toString());
int b = (editText2.getText() == null)?0:Integer.parseInt(editText2.getText().toString());
textView.setText(Integer.toString(a + b));
