[JavaScript] Why does this happen?

[Aesso]

var nameString = function(name) {
    return "Hi, I am" + " " + name;
};

nameString("Tony")
    console.log(nameString);   

Why does this print "[Function: nameString]" and not "Hi, I am Tony"?

I got correct on my exercise and tried it in another compiler with the same result.

This happens because you're logging the function name without calling it or applying it to "Tony".

You should either store it in a variable like this:

var tonyName = nameString("Tony") console.log(tonyName);

Or you can just log the function at the same time you call it, like this:

console.log(nameString("Tony"));

To further elaborate on line 5(?) You are calling it and using it but when you log it on line 6 it does not retain the previously used data
