Javascript objects and arrays issue

Question

I am working on a project and I am stuck at a point that I did not think was that hard. I have an array that looks like the following:

    var Coords = [
        {lat: 7, lng: 3},
        {lat: 3, lng: 2}
    ]

I need to use a loop to push more lat and lng coordinates into this array...actually about 30,000 more coordinates. (Please note that the current data in there is an example.) I have tried doing:

Coords.push(Coords[2].lat = 100)
Coords.push(Coords[2].lng = 200)

and that does not help. Any help, with this simple problem would be great! I can figure out the loop just need to know how to get data in!!

You'd just pass one of those object literals to .push() - not entirely sure what you're asking however — Pointy

You shouldn't use an index when using .push(). Push will automatically place the inserted element at the end of your array. In other words, only use indices when you are updating/removing specific elements. Use the object when you are using the push() function. — Evan Bechtol

Just use

Coords.push({lat: 1, lng: 2})

for pushing new data and

Coords[1].lat = 2

for modifying data.

Try:

Coords.push({lat: 100, lng: 200})

You can add multiple objects like that:

Coords.push({lat: 100, lng: 200}, {lat: 150, lng: 250}, {lat: 200, lng: 300})
