Last post, I have learned to develop my first Express App from the course. Basically, it has three routes. When we type "/", "/bye" and "/cat", the app will receive the request and send the matched response to us. But, if we want to send a nice message when users type other texts after slash, what should we do? We can write a "*" route which will run whenever out app gets any request to any url aside from those three routes that we have already defined. app.get("*", function) In the App.js file, we add a new star route, and it will send you a new message whenever you type any undefined request. I run my app, and put some random texts after slash, and hit enter. All I get is "You are a star!". If we move the star route to the top of those three routes, what will happen? The instructor run the app, the result is even though we send the "/", "/bye" or "/cat" request, all we get...
