Question: I'm just starting with `node.js` and `express.js` and trying to create a listener with port 3000 using `app.listen(3000)`.

The problem I'm having is when I first load the app, the browser loads it just fine, but when I make some changes, save the file and reload the browser, it doesn't show any changes. Mean it is just showing the first loaded version.

I have read many Q/A but none provide the specific solution. I don't know what I'm missing or doing wrong. Any help would be much appreciated, or please let me know if I explained my question properly.

Answer: 
you have to restart the server or install nodemon
This might be a problem with your computer console, probably be an old mac, because I face the same problem as well, try and destroy all node action by using `killall node` for mac and for window computer `taskkill /im node.exe /F` this will terminate all node action on your computer, after restart the node server this should work if it doesn't kindly comment below
