Unexpected token for spread operator.

// app/assets/javascripts/currentUser.js
variable = {
  a: 'a',
  b: 'b'
}

export default {
  toJSON: function() {
    return {...variable};
  }
};

Currently throws an unexpected token while this is a valid syntax.

$ eslint app/assets/javascripts/currentUser.js

app/assets/javascripts/webpack/currentUser.js
  8:13  error  Unexpected token ..

✖ 1 problem (1 error, 0 warnings)

I did this on a fresh npm install eslint.

For eslint to support rest spread usage you need to enable the experimentalObjectRestSpread option under parserOptions 👍

Example:

{
  "extends": "airbnb",
  "parserOptions":{
    "ecmaFeatures": {
      "experimentalObjectRestSpread": true
    }
  }
}

@hzoo is correct. We do not support object spread.
