How to find a min/max with Ruby
You can do
[5, 10].minor
[4, 7].maxThey come from the Enumerable module, so anything that includes Enumerable will have those methods available.
v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.
@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].
[4, 5, 7, 10].minmax=> [4, 10]
All those results generate garbage in a zealous attempt to handle more than two arguments. I'd be curious to see how they perform compared to good 'ol:
def max (a,b) a>b ? a : bendwhich is, by-the-way, my official answer to your question.
