Can i use for loop here instead of writing hundred lines of code.

This is my function. now its suck when there is 200 id.i don't want to write till 200 id's. can i use for loop here ? like this 

for(i=0;i<200;i++){
  "areas": [ {"id": i}]
}

this is my function 

var continentsDataProvider = {
 "map": "continentsLow",

"areas": [ {
  "id": 1,
}, {
  "id": "2",
}, {
 }, {
  "id": "3",
}, {
 }, {
  "id": "4",
}, {
 }, {
  "id": "5",
}, {
  } ]

};

You can use a for loop to create the objects or you can use (the much nicer) Array.from:

var continentsDataProvider = {
  "map": "continentsLow",

  "areas": Array.from({ length: 200 }, function(k, v) { return { id: v + 1}; })
};

console.log(continentsDataProvider);

As noted by Emil S. Jørgensen in the comments - Array.from is not supported by internet explorer so you'll need to polyfill it (polyfill code).

Yes you can, simply try

If your object is

var continentsDataProvider = {
  "map": "continentsLow",
  "areas": []
};

Run your for-loop as

for(var i=1;i<=200;i++){
  continentsDataProvider.areas.push( {"id": i});
}
