Centroid of svg path element

[ALEI REYES]

Is there an easy way to calculate the centroid of the svg path element?

currently, I am using this approximation:

function getCentroid(el){ 

    var pah = el.attr("path");

    var cnt = 0;

    var ans={x:0,y:0};

    for(var i=0;i<path.length;i++){

        if(path[i][0]=='M' || path[i][0]=='L'){

            ans.x+=path[i][1];

            ans.y+=path[i][2];

            cnt++;

        }

    }

    ans.x/=cnt;

    ans.y/=cnt;

    return ans;

}
