how to pass data from controller to javascript in codeigniter?

//controller
public function file_upload(){
         
        $targetPath = "assets/uploads/";
        
            
            $data['targetPath'] = $targetPath;
            $this->load->view('test', $data);
}


//JavaScript in view


                if(percent = 100)
                {
                    $('#progressBar').hide();
                    _("status").innerHTML = tp;
                    
                    console.log(tp);
                } 
            }
