What is the best way to add a new item to an object using its index value?

Can the Locations object have a new property added to it?

The property to be added is:

2:{
   name: "Japan",
   lat: 36, 
   lng: 138,
   description: 'default',
   color: 'default',
   url: 'default'
} 

The current Locations object looks like this:

var locations = {
        0: {
            name: "New York",
            lat: 40.71, 
            lng: -74.0059731,
            description: 'default',
            color: 'default',
            url: 'default',
            size: 'default'
        },
    1: {
        name: "London",
        lat: 51.5073346, 
        lng: -0.1276831,
        description: 'default',
        color: 'black',
        url: 'default',
        type:'square'
        }
}

If we add the new property, the Locations object will look like this:

locations:{
        0: {
            name: "New York",
            lat: 40.71, 
            lng: -74.0059731,
            description: 'default',
            color: 'default',
            url: 'default',
            size: 'default'
        },
        1: {
            name: "London",
            lat: 51.5073346, 
            lng: -0.1276831,
            description: 'default',
            color: 'black',
            url: 'default',
            type:'square'
            }
        2:{
            name: "Japan",
            lat: 36, 
            lng: 138,
            description: 'default',
            color: 'default',
            url: 'default'
} 
    }

Answer №1

One simple way to achieve this is by:

locations[3] = {
   name: "Australia",
   lat: -25, 
   lng: 135,
   description: 'default',
   color: 'default',
   url: 'default'
}
