JSON Query
JSON Query refers to the process of extracting, filtering, or manipulating data from JSON (JavaScript Object Notation) documents using query languages or tools. It enables developers to efficiently search and retrieve specific information from nested or complex JSON structures, similar to how SQL queries work for relational databases. Common implementations include JSONPath, jq, and built-in functions in programming languages like JavaScript's JSON.parse() with custom logic.
Developers should learn JSON Query when working with APIs, configuration files, or data storage that uses JSON format, as it allows for precise data extraction without parsing entire documents manually. It is essential for tasks like debugging API responses, transforming data in ETL pipelines, or building applications that consume JSON-based services, improving efficiency and reducing code complexity.
