Babel Syntax Object Rest Spread

A Babel plugin that allows parsing of object rest/spread syntax (e.g., `const { a, ...rest } = obj;` or `const clone = { ...obj }`) in JavaScript. Current version is 6.13.0, part of the Babel 6 ecosystem. This plugin only enables parsing; transformation requires a separate plugin like `babel-plugin-transform-object-rest-spread`. It is syntax-only and does not include any runtime polyfills. Use with Babel 6; for Babel 7+, use `@babel/plugin-syntax-object-rest-spread`.
