Two if statements in node js

In the following code, I want to read the parameters from the link and display them. I used two separate if statements to check each parameter. The problem is it only reads the first if statement and discards the second one (does not check the second parameter):

var http = require('http');
var url = require('url');
var server = http.createServer(function (request, response) {
  if (request.method == 'GET') {
    var queryData = url.parse(request.url, true).query;
    response.writeHead(200, {"Content-Type": "text/plain"});
    // if parameter is provided
    if (queryData.name) {
      response.end('Hello ' + queryData.name + '\n');
    } else {
      response.end("Hello World\n");
    }
    if (queryData.age) {
      response.end('Your age is ' + queryData.age + '\n');
    } else {
      response.end("No age provided\n");
    }
  }
});
// Listen on port 3000, IP defaults to 127.0.0.1 (localhost)
server.listen(8081);

The link is:

http://127.0.0.1:8081/start?name=john&age=25

Do not use response.end. Instead use response.write and add an response.end() after both if-statements.

See docs: https://nodejs.org/api/http.html#http_response_write_chunk_encoding_callback

Try response.write in the first if block.
