MongoDB syntax error - json

Question

I am having trouble with the syntax (SyntaxError: Unexpected token ILLEGAL) in MongoDB. This command was copied directly from a MongoDB instruction PDF and I cannot find out what is wrong.
Also I don't know if it is relevant but I am using Codeanywhere with a MEAN stack.
db.restaurants.insert(
{
"address" : {
"street" : "2 Avenue",
"zipcode" : "10075",
"building" : "1480",
"coord" : [ ­73.9557413, 40.7720266 ],
},
"borough" : "Manhattan",
"cuisine" : "Italian",
"grades" : [
{
"date" : ISODate("2014­10­01T00:00:00Z"),
"grade" : "A",
"score" : 11
},
{
"date" : ISODate("2014­01­16T00:00:00Z"),
"grade" : "B",
"score" : 17
}
],
"name" : "Vella",
"restaurant_id" : "41704620"
}
)

Answer 1

Try to replace:
"coord" : [ ­73.9557413, 40.7720266 ],
with:
"coord" : [ ­73.9557413, 40.7720266 ]
The comma at the end of subdocument is extra.
By the way, the JSON standard allows only double quoted string as property key, thus, try also this variant:
"coord" : [ "­73.9557413", "40.7720266" ]
I checked your entire JSON-document with a JSON validator, here is a valid version:
{
"address": {
"street": "2 Avenue",
"zipcode": "10075",
"building": "1480",
"coord": ["73.9557413", "40.7720266"]
},
"borough": "Manhattan",
"cuisine": "Italian",
"grades": [{
"date": "20141001T00:00:00Z",
"grade": "A",
"score": 11
}, {
"date": "20140116T00:00:00Z",
"grade": "B",
"score": 17
}],
"name": "Vella",
"restaurant_id": "41704620"
}
