JSONPath is a powerful query language designed for navigating and extracting data from JSON documents. It is similar to XPath for XML, providing a syntax and a set of functions to specify parts of a JSON document and extract data.

Key Features of JSONPath
XPath-Like Syntax: JSONPath uses a syntax that is reminiscent of XPath, making it familiar to those who have worked with XML.
Filtering: Allows for filtering of arrays and objects, making it possible to extract specific elements based on conditions.
Wildcards: Supports wildcards to select all elements in an object or array.
Recursive Descent: Facilitates deep searching within JSON objects.
JSONPath Syntax
Root Node: $
Dot Notation: $.store.book (equivalent to $['store']['book'])
Bracket Notation: $['store']['book']
Wildcard: *
$.* or $['*'] selects all elements
Recursive Descent: ..
$.store..price selects all price elements in the store
Array Slicing: [:n], [start:end], [start:end:step]
$.store.book[0:2] selects the first two books
Filtering: [?(expression)]
