Hi. I'm ahmed, a Rails enthusiastic and i use in my daily life as a developer. This will hopefully be a series in which i write on small(tiny-tips) i discover while coding Ruby.
Whenever you need to get the maximum and minimum value in any enumerable list. It returns a tuple which is an array of exactly two items(because tuples are not types in Ruby!). The first item being the
min and the second being the
[1,2,3,4,5,6].minmax # => [1,6]
The list does not even have to be in any specific order, you can also use it with enumerables that are not ordered.
[6,1,5,10,9,0].minmax # => [0,10]
Get the farthest between a group of dates(with Rails extensions)
[3.days.from_now, 1.day.from_now, Date.today].minmax #=> [Thu, 28 Oct 2021, Sun, 31 Oct 2021 15:00:38.694977000 CDT -05:00]
Hope you have a great day!. Happy Coding.
