            //document.write(alert(m));
            string += '<tr><td>'+(index+1)+'</td><td>'+product['_id']+'</td><td>'+product['name']+'</td><td>'+product['category']+'</td><td>'+product['price']+'</td><td>'+product['manufacturer']+'</td><td><a href="/profile/dashboard/update/{{m}}">Update</a> </td></tr>';
        });

route code

You need to use this quotes `` for template string;

as example:

var m = 1;
var string = `id: ${m}`

`... <a href=/profile/dashboard/update/${product['id']}>Update</a> </td></tr>`

You need to wrap your whole string in backticks and pass the variables as written above ( ${var_name} ). See this answer for more info. This isn't a NodeJS question, more of a Javascript question itself.

string += '<tr><td>'+(index+1)+'</td><td>'+product['_id']+'</td><td>'+product['name']+'</td><td>'+product['category']+'</td><td>'+product['price']+'</td><td>'+product['manufacturer']+'</td><td><a href="profile/dashboard/update/'+id+'">Update</a> </td></tr>';

It will work
