If you want to pass multiple variables in the request, you can pass it in the following way:

var emailVar = "someEmail@gmail.com";
var nameVar = "someName";
var url = `/home?email=${emailVar}&name=${nameVar}`;
//Now make the request.

and in the backend logic, you can retrieve these values as:

app.get('/home', function(request, response)
{
    console.log(request.query.email+"  "+request.query.name);
    var email = request.query.email;
    var name = request.query.name;
    response.setHeader('Content-Type', 'application/json');
    if(request.query.email)
    {
        response.send(JSON.stringify({
            message: 'Got the email'
        }));
    }
    else
    {
        response.send(JSON.stringify({
            message: 'No email sent'
        }));
    }
});

This approach is useful for performing query operations in the backend.
