Sorting an array in descending order in Ruby.
- by Waseem
Hi,
I have an array of hashes like following
[
{ :foo => 'foo', :bar => 2 },
{ :foo => 'foo', :bar => 3 },
{ :foo => 'foo', :bar => 5 },
]
I am trying to sort above array in descending order according to the value of :bar in each hash.
I am using sort_by like following to sort above array.
a.sort_by { |h| h[:bar] }
However above sorts the array in ascending order. How do I make it sort in descending order?
One solution was to do following:
a.sort_by { |h| -h[:bar] }
But that negative sign does not seem appropriate. Any views?
