Why deterministic JSDoc matters in JavaScript and TypeScript projects

A practical look at why teams should prefer repeatable AST-based documentation over hand-written boilerplate or generated guesses.

Documentation is easiest to trust when the same source code always produces the same result. jsdoc-scribe is built around that idea: parse the AST, infer what can be inferred from syntax, and avoid network calls or AI-generated prose.

The problem with drifting comments

Hand-written JSDoc often starts useful and slowly falls behind. Parameter names change, return values evolve, and old comments remain in place. Drift checks make documentation a real part of code quality instead of a one-time cleanup task.

Good documentation should fail loudly when it no longer describes the code.

Where jsdoc-scribe fits

Use gen-comments to add missing blocks, gen-docs to publish reference pages, and lint or drift checks in CI to keep everything honest over time.
