Jora

Jora is a JavaScript object query engine and language for processing and querying JSON-like data structures efficiently. While currently in a beta development phase (v1.0.0-beta.15), it is considered stable, though its syntax might undergo changes in future releases. The project maintains a relatively frequent release cadence for beta versions, actively introducing new features, improvements, and addressing issues. Jora distinguishes itself with a compact, JavaScript-like syntax for common data manipulation tasks, tolerant query execution that simply returns nothing for unreachable paths instead of throwing errors, and automatic aggregation and deduplication of values. It also includes advanced features like a stat collecting mode for powering suggestions in editors and an extensible Domain Specific Language (DSL) via custom methods and assertions, making it highly adaptable for complex data transformations. It is a core component within the Discovery.js ecosystem, used for data visualization and building interactive reports.
