var result_array = [];

var current = null;
var cnt = 0;
for (var i = 0; i < array_elements.length; i++) {
    if (array_elements[i] != current) {
        if (cnt > 0) {
            result_array.push([current,cnt]);
        }
        current = array_elements[i];
        cnt = 1;
    } else {
        cnt++;
    }
}
if (cnt > 0) {
    result_array.push([current,cnt]);
}

result_array.sort(function(x,y) {return y[1] - x[1]})
alert(result_array);

The result_array will have the result.
