Babel TypeScript Preset

`@babel/preset-typescript` is a Babel preset specifically designed to strip TypeScript syntax from source code, converting it into standard JavaScript. It does not perform any type checking; its sole purpose is to remove type annotations, enums, and other TypeScript-specific constructs so that Babel can continue processing the resulting JavaScript. This allows developers to leverage Babel's extensive plugin ecosystem for further transformations, such as targeting older JavaScript environments with `@babel/preset-env` or integrating JSX transformations. The package is part of the Babel monorepo, maintaining an active release schedule with frequent patch and minor updates (often bi-weekly) and new major versions released periodically. As of April 2026, the `7.x` series is stable, with `7.29.2` being a recent patch, while the `8.x` series is in a release candidate phase, with `8.0.0-rc.3` being the latest. Its primary differentiator is enabling a unified transformation pipeline for projects using TypeScript in conjunction with various Babel features that the TypeScript compiler alone does not provide.
