Node JS course UPDATE?

Hi I’m new to the community,
I want to ask about the NodeJS course last update date, Please.
Should I enroll the course now or wait or it’s already up to date ?

The course is from 2018.

The course is not up to date and he is using joi 13.1.0 which is deprecated and is not working with version 17 of joi

Will there be an update?
For the node course
Or it’s okay to join because it’s using joi which is not recent

Please is it possible to watch the video offline after buying the Course?
