Ruby Hashes Programs

In Ruby programming language, 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.

This section contains Ruby hashes programs, practice these Ruby programs to learn the concept of Ruby hashes, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Ruby hashes programs.
