Generating JSON in Ruby

In Ruby, the JSON.generate method allows you to convert a Ruby hash or array into JSON format. Simply provide a Ruby hash or array as input to this method, and it will produce a JSON string as output. This makes it convenient for creating JSON data from within your Ruby code.

Example:

Ruby

require 'json'

ruby_hash = {"name" => "Bob", "age" => 30, "city" => "New York"}

json_string = JSON.generate(ruby_hash)

puts json_string

Output:
