Hash sort

WebHash. A Hash is a dictionary-like collection of unique keys and their values. Also called associative arrays, they are similar to Arrays, but where an Array uses integers as its index, a Hash allows you to use any object type. Hashes enumerate their values in the order that the corresponding keys were inserted. WebOct 11, 2015 · The easiest way to sort a hash by the value in its key-value pairs is to use the #sort_by method. To make #sort_by use the values to sort the pairs, use this code block: { key,value value }. This tells #sort_by to perform its default alphanumeric sort on the hash, based on the values in the key-value pairs instead of the keys.
