Enumerable#tally in Ruby 2.7

The tally method has been added to Enumerable in Ruby 2.7

It's a simple little method and as the name suggests, it tallys things for us! It affords us a much simpler way to group items and count their occurrence.

We could always count the size of an array.

fruit_bowl = ["apple", "pear", "pear", "banana", "apple"] fruit_bowl.count => 4 

We could count how many of each item an array contained.

fruit_bowl.each.count("apple") => 2 

Now we can easily take stock of our array items with tally which will return us a list of items with their respective counts.

fruit_bowl = ["apple", "pear", "pear", "banana", "apple"] sorted_fruit = fruit_bowl.tally => {"apple"=>2, "pear"=>2, "banana"=>1} sorted_fruit["apple"] => 2 

Sweet as 🍓😋
