Get Array's Min and Max with minmax
In ruby, you can get the minimum value in an array with #min and the maximum value with #max.
But sometimes you need both the min and max, and it feels a waste to make two separate calls. Turns out you can get both in one with #minmax - which will return a two element array with the min and max values.
pry(main)> [1, 2, 3].minmax
# => [1, 3]You can also pass it a block for custom ordering criteria.
