Regarding function expressions, you've omitted to mention that you can name functions defined in this manner - and in fact it can be a good idea to do so. If they are not named they will show up as 'anonymous' functions in stack traces. So, it is equally valid to write:

const calcAge2 = function calculateAge(birthyear) {
    return 2021 - birthyear;
}
Enter fullscreen mode Exit fullscreen mode

In this case, stack traces involving the function will show the name calculateAge instead of 'anonymous function'
