问题
I downloaded some JSON, as shown below. In the developer console it looks like an object containing nested objects which contain nested objects ...
I would like to add a new, empty "campaign" into the data (at the front). How do I do that?
Insert
var blankCampaignData = {'title': '', 'description': '', 'path_to_logo': '', 'start_time': date, 'end_time' : date, 'paused': false};
into

Work out what the next campaign id should be:
var nextId = +Object.keys(obj.campaigns).sort().pop() + 1;
Add the empty campaign to the campaigns object. Obviously you'll need to define date beforehand.
obj.campaigns[nextId] = {
'title': '',
'description': '',
'path_to_logo': '',
'start_time': date,
'end_time' : date,
'paused': false
}
