babel-plugin-pure-calls-annotation

A Babel plugin (v0.4.2, stable, low release cadence) that automatically adds /*#__PURE__*/ comments to call expressions in variable declarators, assignment expressions, call arguments, and other expression contexts. This helps bundlers like Webpack identify side-effect-free calls for tree shaking and dead code elimination. Unlike manual annotation, it eliminates human error and ensures consistent coverage across large codebases. Ships TypeScript types and integrates seamlessly into any Babel-based build pipeline.
