Unexpected token `..` when using spread operator in function arguments

The following code:

function mergeAndConcat(...objects) {
   // stuff
}

Is throwing error Unexpected token .. on line 3, which is the function definition. I’ve got the spread option set to true in the ecmaFeatures section of my config, so I wouldn’t expect the above to cause an error.

Thanks in advance 😃

That’s not a spread operator, it’s a rest parameter. You need to enable the restParams flag.

Somehow restParams is missing in the documentation, but it is mentioned in the documentation of espree.

I believe all concerns have been addressed here, so closing.
