babel-jscs

babel-jscs allows linting all valid Babel code with JSCS by providing a custom parser (esprima) that monkeypatches JSCS to support Babel syntax. The package is experimental, last released as 3.0.0-beta1, and is intended to be integrated into JSCS itself via the --esnext flag. It is not actively maintained and is superseded by ESLint and babel-eslint. Key differentiator: enables Babel syntax support for JSCS users before JSCS natively supported it.
