I'm working on upgrading ESLint to version 4. As of version 4.7.0, ESLint supports autofixing for processor plugins. https://eslint.org/blog/2017/09/eslint-v4.7.0-released We should investigate updating the self-hosted js plugin to support autofix. This would help autofix to work correctly across the whole tree (currently running a full tree-fix, stops fixing part way when the js plugin is required).
