Babel Core

Babel compiler core version 6.26.3. This is an outdated version of Babel (pre-7.x). The current stable releases are v7.29.2 (2026-03-16) and v8.0.0-rc.3 (2026-03-16). babel-core v6 is no longer maintained and should not be used for new projects. Key differentiator vs v7/v8: v6 uses the `babel-core` package while v7+ uses `@babel/core`. It provides core transformation API including `transform`, `transformFile`, `transformFileSync`, and `transformFromAst` methods. Compatible with Node.js and browsers via bundlers. Does not include presets/plugins; those are separate packages.
