I have on my site form with input date, which I am now returning as Date - RFC 3339.
I want to have ISO 8601 - value of input date to looks like 2021-12-8T04:30:00-06:00. Convert date RFC 3339 to date in format ISO 8601. Is there some method to do that? Or some library to javascript I can use?
const dateTaskField = document.querySelector('#new-task-date');
dateTaskField.valueAsDate = new Date();<input type="date" id="new-task-date">Solved by assigning it to new Date() function:
const endDateIso = new Date(dateTaskField.value).toISOString();
