DateFormat

Easily check what your Date will look like in your format.

I have chosen the approach of explicitly adding a comment to see the format due to automatically showing it. This is due to identifying a valid ISO format. There are too many combinations of languages and functions for date formatting, and blindly regex matching would result in a lot of false positives. If anyone wants to attempt this approach, feel free to adapt.

Using the extension

Add [comment] ^df (dateformat) under any string (surrounded by quotes) to see the date in the chosen format. Use the command dateformat: insert-date to do this automatically at your cursor. Easily edit this on the fly and watch it update in real time.

By default it will use Date.now(), but you can override this in setting by passing in an ISO 8601 of your choice.
