Ruby - Hash Creation Literal
Introduction
There is a shorthand way of creating Hashes and initializing them with key-value pairs.
Just add a key followed by => and its associated value.
Each key-value pair should be separated by a comma and the whole lot placed inside a pair of curly brackets:
Demo
h1 = {'room1'=>'A',
'room2'=>'B',
'loc1' =>'C',
'loc2' =>'D' }
puts h1# from ww w . j ava 2 s. c o m
Result
