How to remove square brackets in a Javascript array?

I have an array called value and when I console.log(value) I get about 30 lines of code with the following [6.443663, 3.419248]

The numbers change as they are Latitudes and Longitudes. But I need to somehow get rid of the square brackets around each one.

I tried var replaced = value.toString().replace(/\[.*\]/g,''); but this changed the above example to 6.443407,3.419035000000008 and failed my code.

In other words I need help getting rid of square brackets in an array in order to plot points on my map.

My array is made up from the following code because each latitude and longitude value is held within onClick functions within a links. So a member on here kindly supplied the below code to get my values into an array but now I'm struggling to get the values out without any brackets ruining it.

var obj = {};
$('.choice-location-inner a').each(function(){
    var $this = $(this);
    var text = $this.attr('onClick').replace('findLocation(\'', '').replace('\');return false;', '');
    var array = text.split(',')
    obj[this.id]= [parseFloat(array[0]), parseFloat(array[1])];
});

The array is trying to plot markers on my Google Map using the following code

$.each(obj , function(index, value){
    geocoder = new google.maps.Geocoder();

    geocoder.geocode( { 'address': value}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
            marker = new google.maps.Marker({
                map: map,
                icon: image,
                position: results[0].geometry.location
            });
        } else if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            wait = true;
            setTimeout("wait = false", 1000);
        } else {
            alert("Geocode was not successful for the following reason: " + status);
        }
    });
});

If you need a clean input you can write this.

var justTheDataWithoutSeparation = data.split('');

of course, if you want to separate with commas or something else, you need to add

vat dataSeparatedWithSomething = data.split('-');

You need to be careful because doing this method can cause your data to set like string value, and may affect your output, you need to convert that before.

`${arr.map(({ id }) => id)}`

Maybe this way a lot simple other than using inbuilt functions!

transforms the line to array to text.

var value = [[1234213, 1234231], [1234213, 1234231]];
var dato = value[0];
console.log(dato.toString());

Unless I've misread and the item is an object rather than a string with brackets contained, the you could just access it by its sub array poition

lat = obj[this.id][0]
lng = obj[this.id][1]

perhaps?

It looks like you want the comma separated string representation of the array. If that's the case, you can do this:

var commasep = value.join(",");
