The usage of a white-space as delimiter between date and time isn't specified by ISO 8601, but is allowed by the RFC that is mostly used on the web. Most Browsers and JavaScript libraries support and output `ISO 8601` formatted dates with date+time delimited by a white-space (`Chrome` (`Blink`/`Chromium`); `Firefox` (`Gecko`); `FeathersJS`; ...).

Note that ECMAScript spec is "date-times based upon a simplification of the ISO 8601"[1], not a ISO 8601 or RFC. So using space here is implementation-dependent behavior (spec only accepts "T" case.) But it can be a good extension.
