Tern errors out with object spread

[FuzzOli87]

I've been having issues with tern staying up after updating my plugins. This is the error received:

I'll do some more debugging if I have time!

@FuzzOli87 looks like this is ternjs plugins bug.

@carlitux I did a bit of digging and found that object spread causes tern to break and I'm not sure if the fault lies in the request that is sent or tern itself:

const obj = {
  hi: 'hello'
};

const newObj = {
  hello: 'hi',
  ...obj
}

The above will fail as soon as I type the second (.) in the spread. The request sent is:

Request: {
  "query": {
    "type": "completions",
    "types": false,
    "depths": false,

    }
  ]
}

        if (prop.key.name == "__proto__") {
                     ^

TypeError: Cannot read property 'name' of undefined

Tern recently updated so they might of changed something. This worked fine before!

@carlitux I just installed tern 0.21.0 and it works again. So I'll open up an issue on there. It wasn't a major release version so I didn't think it would break anything.

cool, thanks for update

This was not an issue with this library but with tern and has been fixed by 0.22.2.
