I get Unexpected token error whenever I run the code against jslint while using '...' notation. I am using grommet-toolbox for Grommet UI (and UI/UX framework for React) and so when I run gulp dev mand I get this error, thereby not being able write code like below:

return {...state, fetching: true}

(The above code is in line 10 of this file: .js)

How to resolve this issue?

• 1 It's not ES6/2015 and not ES2016 but not standardised syntax. You must use babel-eslint for it to work. – zerkms Commented Jul 25, 2016 at 9:53

The Object spread operator is not a ECMASCRIPT STANDARD, while Array spread operator is. So, probably this is the reason of your lint-issue.

You can find further information here: https://github./sebmarkbage/ecmascript-rest-spread

Just a note, I suggest you to have a look at eslint because is the mon linter used for esnext (it is pluggable and maybe has a solution to avoid this issue).

Instead of using spread operator, please try to use Object.assign, they ought to acplish the same thing. Just without jshint outputting warnings/errors.
