write_file_with_write.rb
This Ruby code snippet demonstrates creating a JSON file. It first requires the json
library. Then, it defines a hash with a key-value pair. Finally, it writes the hash to a file named file.json
within the input/json/
directory, converting the hash into a JSON string using JSON.dump
. The return value ‘15’ represents the number of bytes written to the file.
Ruby code snippet
require 'json'
#=> true
hash = {:key => 'value'}
#=> {key: "value"}
File.write('input/json/file.json', JSON.dump(hash))
#=> 15
