Babel Plugin for TypeScript Transformation

This package, `@babel/plugin-transform-typescript`, is a core Babel plugin designed to strip TypeScript type annotations from code, transforming it into standard ECMAScript. It operates solely on the syntax level and does not perform any type-checking; users must integrate the TypeScript compiler (tsc) separately for type validation. The current stable major version is 7 (e.g., v7.29.2 as of March 2026), with active development ongoing for Babel 8, which is currently in release candidate stages (e.g., v8.0.0-rc.3). Babel maintains a frequent release cadence for patch versions and rolls out minor/major updates periodically. A key differentiator is its focus on pure syntax transformation, which makes it faster than a full TypeScript compilation but also means it explicitly does not support TypeScript-specific features like `namespace` declarations, `const enum`s, or the legacy `export =` and `import =` syntax, as these features require type information for meaningful transformation.
