object JsPath extends JsPath

Companion object and root path.

For an object { "name": "foo" }, the path to the name property is:

import play.api.libs.json.JsPath

JsPath \ "name"

For an object { "id": 1, "nested": { "score": 0.12 } }, the path to the nested score is:

import play.api.libs.json.JsPath

JsPath \ "nested" \ "score"
