javascript - app.set('port', 8080) versus app.listen(8080) in Express.js

Question

I\'ve been trying to use Express.js to launch a website. At first, I was using app.set(\'port\', 8080) but the browser was unable to connect to the page. Afterwards

Answer 1

For example:

var port = 8080
app.listen(port);
console.log(`Listening on port ${port}`);

Line by Line Explaination:

var port = 8080; =>Creates a variable(everything in javascript is an object) and sets the port location to localhost 8080 app.listen(port); =>The application made using express module checks for any connections available and if yes then it connects and the application launches console.log('Listening on port ' + port); =>Displays the message onto the terminal once deployed successfully
