You're re-designing a blog, and the blog's posts have the Weekday Month Day, time format for showing the date and
time when a post was made, e.g., Friday May 2, 7pm.
You're running out of screen real estate, and on some pages you want to display a shorter format, Weekday Month Day
that omits the time.
Write a function that takes the website date/time in its original string format and returns the shortened format.
Input will always be a string, e.g., "Friday May 2, 7pm".
Output will be the shortened string, e.g., "Friday May 2" .
def shorten_to_date(long_date)
long_date.split(',').first
end
