read_with_parse.rb(json)

This Ruby code performs the following tasks:

  1. It requires the ‘json’ library, which is a standard library in Ruby for parsing and generating JSON (JavaScript Object Notation) data.

  2. It reads the contents of a file named ‘file.json’ using the File.read method. This method reads the entire contents of the file as a string.

  3. It then parses the JSON content using JSON.parse. This method takes a JSON string as input and converts it into a Ruby data structure, typically a hash or an array, depending on the JSON structure.

So, in summary, this code reads the contents of a JSON file named ‘file.json’ and converts it into a Ruby data structure for further processing within the Ruby program.

Execution:

require 'json'
#=> true
JSON.parse(File.read('file.json'))
#=> {"key"=>"value"}
