Encoding - Standard Library

Encoding is the process or marshaling or unmarshaling data into different forms. Taking JSON string documents and convert them to values of our user defined types is a very common practice in many go programs today. Go's support for encoding is amazing and improves and gets faster with every release.

Notes

  • Support for Decoding and Encoding JSON and XML are provided by the standard libary.
  • This package gets better and better with every release.
