read_with_open.rb

This Ruby code snippet demonstrates reading and parsing a JSON file. It first requires the json library. Then, it opens a file named ‘file.json’ located in the ‘input/json/’ directory, reads its contents, and parses it as JSON using JSON.load, resulting in a Ruby hash (in this case, {"key" => "value"}).

Ruby code snippet

require 'json'
#=> true
File.open('input/json/file.json') {|j| JSON.load(j)}
#=> {"key" => "value"}
