It seems like you don't need to do that mapping at all, it works without it.

So just use "dataProvider": pie,

Here's a working version on JSFiddle.

[pie.map((e)=>{return {
              "location": e.location, //here is the error
              "value": e.value //here is the error}
            }})]

First { is for function and second is for object.

heres the controller:

    $branch_emp = $this->mainModel->getbranchwise();

            foreach ($branch_emp as $data)
            {
                $series_data[]= array('name'=>$data['branch_name'],'data'=>array($data['totalemp']));
            }
$data['branch_emp']=json_encode($branch_emp);


 <script type="text/javascript">
        $(function () {
            var temp = <?php echo $branch_emp; ?>;
            console.log(temp);
            $('#pie_chart').highcharts({
                chart: {
                    type: 'pie',
                    options3d: {
                        enabled: true,
                        alpha: 45,
                        beta: 0
                    }
                },
                title: {
                    text: 'Pie Chart of Employees'
                },
                tooltip: {
                    pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
                },
                plotOptions: {
                    pie: {
                        allowPointSelect: true,
                        cursor: 'pointer',
                        depth: 35,
                        dataLabels: {
                            enabled: true,
                            format: '{point.name}'
                        }
                    }
                },
                series: [{
                    type: 'pie',
                    name: 'Browser share',
                    data: temp.map(function(e){
                        return [e.branch_name,e.totalemp];
                    })
                }]
            });
        });
    </script>
