babel-eslint

I would like that too! I don't think there have been any features added since the last one with Babel 6 release. Yeah there's multiple JavaScript parsers: esprima, acorn, shift, babylon (uglify has their own parser I think). There was an effort to standardize as well in https://github.com/estree/estree. EDIT: However, in Babel 6 there were a few (nice) incompatible changes to the AST which was unfortunate for interop and other tools (https://github.com/babel/babel-eslint had to make a lot of changes). I don't want to speak for him, but I think a lot of the decisions to fork (parser, etc) at the time were most likely made like mentioned above to move faster. And at the time, Sebastian was basically the only one working on it. Maybe more context from his post: https://medium.com/@sebmck/2015-in-review-51ac7035e272#.qcyz...

You can use babel-eslint [0] and the eslint-loader [1] to catch all errors babel might have. [0] https://github.com/babel/babel-eslint [1] https://github.com/MoOx/eslint-loader
