Is moment.js still the preferred library for wrapping JavaScript DateTime ?

Hi there,
In lesson 1 exercise 7, the syllabus recommends using moment.js to calculate the number of nights. I looked up the documentation of moment.js, and it says: We now generally consider Moment to be a legacy project in maintenance mode. It is not dead, but it is indeed done.
I ended up using luxonwhich is recommended in themoment.js` documentation.
I understand that for completing the exercise, this probably doesn't matter much, but it would be nice to learn the more updated and preferred technology in the course.
If you think this could be a good idea, I could create a pull request to fix it.
