tgo Compiler Gains Lodash Support by Parsing JSDocs as Live Type Data

A developer working on the tgo JavaScript-to-Go compiler spent two weeks attempting to add Lodash library support, repeatedly hitting dependency chain issues. A key breakthrough came when they discovered that Lodash includes JSDoc strings describing internal function types, and that the TypeScript compiler can natively parse them. The tgo compiler was updated to extract those JSDocs and automatically generate type information, significantly expanding Lodash compatibility. The experience prompted broader reflections on why traditional written documentation often fails in practice, arguing that well-named functions and parseable annotations serve as more reliable 'functional documentation' than static text. The developer contends that only documentation which can be tested or executed — rather than merely read — provides lasting value in real-world software projects.
