Interactive JsonPath tutorial

Object Identifier-Index: .foo

The simplest useful filter is $.foo. It produces the value at the key "foo", or empty list if there's none present.

For example given input {"make": "Nissan", "model": "Kicks"} and filter $.make it produces "Nissan"

Now you try to create a JQ expression that would product the result.

Input:
1{
2  "firstName": "Charles",
3  "lastName": "Doe"
4}
JsonPath expression:
Expected:
1[
2  "Charles"
3]
