What is TypeScript?

TypeScript is a strongly-typed superset of JavaScript that compiles to plain JS. Its type system catches errors at build time and powers editor tooling across the ecosystem.

Smart Stack indexes the official TypeScript documentation and keeps it current, so you can search it directly or ask questions in plain language. Because answers are grounded in the real pages — not a model's training data — you get correct, version-aware APIs instead of plausible-looking guesses.

TypeScript — FAQ

What is the latest version of TypeScript?
The latest version of TypeScript indexed in Smart Stack is 5.7.0. Smart Stack re-checks sources on a schedule, so answers stay current with releases rather than relying on a model's training cutoff.
Where can I find the official TypeScript documentation?
The official TypeScript documentation lives at https://www.typescriptlang.org/docs/. Smart Stack indexes it so you can search across it — and the rest of your stack — and get AI answers grounded in those exact pages.
Can I search TypeScript docs together with the rest of my stack?
Yes. That's the core idea behind Smart Stack: add TypeScript to your stack alongside your other tools, and the AI answers questions using the official docs for everything you selected at once — no tab-switching.
Does Smart Stack hallucinate TypeScript APIs?
Smart Stack uses retrieval-augmented generation: it pulls relevant sections from the official TypeScript documentation and grounds the answer in them, which sharply reduces the made-up function signatures you get from ungrounded models.
What works well with TypeScript?
TypeScript is commonly used with tools in the languages space and adjacent layers of the stack. Add them together in Smart Stack to get integration-aware answers that understand how they fit.
