Hi, I’m trying to do this exercise with vs code but when I do ‘node app.js’ in terminal, it returns

Error: Cannot find module ‘express’.

In which file can I find the module ‘express’ to avoid this ?

Thank you!

Why is the fat arrow suggested?

I think it is poor practices to use fat arrows except for “data set manipulation”. Or for very specific reason for using external scope. fat arrows relate to functional programming.

I’ve been wondering, is it possible to pass an actual function into the listen method? I’m thinking something like this:

app.listen(3000, myMethod);

var myMethod = function(){
//Do something
}

Why would that be wrong?

how is app.listen( ) used with app.get( )?
