This is the playground for github.com/theory/jsonpath, a Go package that executes RFC 9535 JSONPath queries to select values from arbitrary JSON data.
The playground runs entirely in the browser thanks to TinyGo, which compiles the github.com/theory/jsonpath package into Web Assembly.
Learn more about JSONPath by reading the IETF JSONPath Standard, and more about github.com/theory/jsonpath by following the links at the bottom of the page. The code for this website can be found on GitHub.
