Here is the data

    var userInfo = {
        'a': {
            id: 1,
            vehicle: 'car'
        },
        'b': {
            id: 2,

            vehicle: 'plane'
        },
        'd': {
            id: 4,
            vehicle: 'plane'
        },
        'e': {
            id: 5,
            vehicle: 'bike'
    }

Answer 1

To add a new property, simply use

Object.Property = //whatever you want here

If there is no property existing, it will create a new one, and if there is already a property then it will overwrite it.

So for your code, you would want

userInfo.f = {id: 6, vehicle: 'bus'}

Answer 2

userInfo.f = {id: 6, vehicle: 'train'};
