How do modern build tools handle TypeScript vs tsc?
WHAT IT TESTS: separating transpilation from type checking for speed. Great answer: fast native tooling strips TS per-file on demand via native ESM; browser loads only visited modules; tsc/ts-loader check/bundle the whole graph upfront.
WHAT IT TESTS: whether you understand that modern dev servers decouple type checking from transformation and use native ESM to avoid upfront bundling. A great answer hits four things: first, Vite uses fast native tooling to strip TS types per file on demand, skipping type checks; second, the browser fetches only visited modules over native ESM; third, tsc and ts-loader type-check and/or bundle the whole graph before serving, so startup scales with app size; fourth, native-speed transforms make per-file work far faster than Node-based…
