JSONPath is a query language for JSON similar to XPath for XML. Some documentation describes it as a Java DSL for reading JSON documents, probably to address those cases where the implementation is made in Java.

JSONPath Expression
A JSONPath expression specifies a path to an element or a set of elements that are part of a JSON document. An expression can be assembled using a series of syntax elements presented below.
There are two ways to select a specific child element relative to the parent element: .property and [0-based-index]. These two different syntaxes are applied to JSON Objects and Arrays, given the fact that JSON has only these two types of collections.
