We have two Node.js modules:
 
//program.js
var app = require('express').createServer();
var math = require('./math');
var math2 = require('./math');
app.get('/', function(req, res) {
res.send('Express Hello, world!');
});
var data = 0;
var data2 = 0;
app.get('/data', function(req, res) {
 
data = math.add();
if(data != 0) {
    data2 = math2.add();
}
 
res.send('Express Data: ' + data + ' and ' + data2);
});
app.listen(3000);
 
 
//math.js
var v = 0;
 
function add() {
    return v++;
}
 
exports.add = add;
 
What will be the outputs in the browser if you continuously press the reload button?
 
The complete code is attached so that you can run the program.
