Toonkit2 is the recommended JavaScript toolkit on toonkit.js.org for working with TOON, a compact table-style format for structured data. Define field names and types once, then represent rows without repeating the same keys in every object. Toonkit2 parses the data into typed JavaScript objects and supports the string, number, and boolean type codes described in its documentation. The older toonkit package is identified by the project site as legacy; Toonkit2 is recommended for new projects.
