How to find a min/max with Ruby

Question

I want to use min(5,10), or Math.max(4,7). Are there functions to this effect in Ruby?

Answer 1

If you need to find the max/min of a hash, you can use #max_by or #min_by

people = {'joe' => 21, 'bill' => 35, 'sally' => 24}

people.min_by { |name, age| age } #=> ["joe", 21]
people.max_by { |name, age| age } #=> ["bill", 35]
