GJSON is a Go package that provides a [fast](#performance) and [simple](#get-a-value) way to get values from a JSON document.
It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array), and [parsing JSON lines](#json-lines).
Also check out [SJSON](https://github.com/tidwall/sjson) for modifying JSON, and the [JJ](https://github.com/tidwall/jj) command line tool.
