흔히 이렇게 알고 있다

TypeScript automatically elides type-only named imports and unused value imports during ECMAScript emit regardless of whether type keywords or verbatimModuleSyntax are configured.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• When compilerOptions.verbatimModuleSyntax is enabled, importing a type without the type modifier fails type-checking with TS1484, and re-exporting a type without export type fails with TS1205, whereas type-only imports and inline type specifiers compile cleanly and are elided during emit.
• compilerOptions.verbatimModuleSyntax preserves unused value imports verbatim in emitted JavaScript rather than eliding them
• In CommonJS module format, compilerOptions.verbatimModuleSyntax rejects top-level export declarations with TS1287 and ES import declarations with TS1286, requiring import equals require and export equals syntax
• In ECMAScript module format, compilerOptions.verbatimModuleSyntax rejects CommonJS export assignment syntax with TS1203
• Specifying removed legacy options importsNotUsedAsValues or preserveValueImports alongside verbatimModuleSyntax produces configuration diagnostics with TS5102
