JSONPath is a query language for JSON documents, similar to XPath for XML. It uses expressions like $.store.book[*].author to query and extract nodes from complex nested JSON structures.

What is the difference between dot notation and bracket notation?

Dot notation ($.store.book) is clean and concise for standard alphanumeric property keys. Bracket notation ($['store']['book-title']) is required when property names contain spaces, hyphens, or special characters.
