You can use String.split() to get the day, month and year for the Date in question.

We can then pass to the Date.UTC() function and then the Date() constructor. (Note: We pass monthIndex to the Date constructor, that's why we subtract 1 from the month )

To display as an ISO string, we can then use Date.toISOString()

const [month, day, year] = '05/23/2022'.split('/');
const date = new Date(Date.UTC(year, month - 1, day));
const result = date.toISOString();
console.log('Date (ISO):', result);

We can also do this easily with a Date / Time library such as luxon.

We'd use the DateTime.fromFormat() function to parse the input string, setting the timezone to 'UTC'.

To output the ISO date, we can use the DateTime.toISO() function:

const { DateTime } = luxon;
const date = DateTime.fromFormat('05/23/2022', 'MM/dd/yyyy', { zone: 'UTC'});
console.log('Date (ISO):', date.toISO())
<script src="https://cdnjs.cloudflare.com/ajax/libs/luxon/2.3.1/luxon.min.js" integrity="sha512-Nw0Abk+Ywwk5FzYTxtB70/xJRiCI0S2ORbXI3VBlFpKJ44LM6cW2WxIIolyKEOxOuMI90GIfXdlZRJepu7cczA==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

We can also do this in moment.js, using moment.utc(), then .toISOString():

const date = moment.utc('05/23/2022', 'MM/DD/YYYY');
console.log('Date (ISO):', date.toISOString())
<script src="https://momentjs.com/downloads/moment.js"></script>

Note that .toISOString() always returns a timestamp in UTC, even if the moment in question is in local mode. This is done to provide consistency with the specification for native JavaScript Date .toISOString(), as outlined in the ES2015 specification.

let date = '24.05.2022 0:00:00';
let parsedDate = moment(date, 'DD.MM.YYYY H:mm:ss')
console.log(parsedDate.toISOString());
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.19.1/moment.min.js"></script>
