Is this course outdated or nah?

I just want to ask if this course is outdated. I am learning the full stack developer course and most of the article and learning material are from 2016, 2015, 2020… Thank you for your answer.

a major update for the paths like Frontend Engineer and Full Stack has been announced for February 11th. Probably the older learning material (regarding mostly external articles, I suppose) will be taken out then.
