Sad but true. Today, we’ll be tackling Friendly Date Ranges, the last bonfire in the entire FCC Bonfires Series. If you’ve made it up to this point, this next exercise shouldn’t pose much of a problem, but we’ll go through it anyway.

This time, we must write a function that given an array containing two strings that representing two dates (in ‘YYYY-MM-DD’ format) returns a human friendly date range. What the hell does that mean?

According to Free Code Camp, it’s a date range with no redundant information, in other words, if both dates are in the same year and month, only display the day range within that month etc. Keep in mind that if starting in the current year, the following year can be inferred by the reader and thus, should not be displayed. But I’ll stop babbling nonsense and show you some examples so we can get started:

['2015-10-04', '2015-10-20'] -> ['October 4th', '20th']
['2015-12-24', '2016-01-03'] -> ['December 24th', 'January 3rd']
['2020-01-21', '2021-05-25'] -> ['January 1st, 2020', 'May 25th, 2021'];
