Today’s Ruby function in Enumerable#max.
Enumerable#max
will find the largest item in an enum of items that are Comparable
.
This means it works against numbers, strings, symbols, or more, as long as that type includes the module Comparable
.
[5, 67, 30, 102, 3, 1].max #=> 102 ['baz', 'bar', 'foo', 'xray', 'z', 'a'].max #=> "z" [:foo, :bar, :baz, :snafu].max #=> :snafu
Enumerable#max
can also take a block of two arguments, allowing you to find the max based off of another property of those objects, such as the length:
['baz', 'bar', 'foo', 'xray', 'z', 'a'].max {|a, b| a.length <=> b.length} => "xray"
