JSONiq

JSONiq is a query and functional programming language designed specifically for querying and processing JSON data. It provides a declarative syntax similar to SQL but tailored for JSON structures, enabling developers to extract, filter, transform, and aggregate JSON data efficiently. It is standardized by the W3C and often used in NoSQL databases and big data applications.

Also known as: JSON Query Language, JSONiq Query Language, JQ (informal, but note: distinct from jq tool), JSON Query, W3C JSONiq

Why learn JSONiq?

Developers should learn JSONiq when working extensively with JSON data in applications such as web APIs, NoSQL databases like MongoDB or Couchbase, or data processing pipelines. It simplifies complex JSON queries, reduces boilerplate code, and improves performance in scenarios requiring data extraction, transformation, or integration, making it ideal for data analysts and backend engineers handling semi-structured data.
