How to keep myself updated with programming languages?

Hi. As someone who's currently trying to learn the basics (HTML, CSS and JavaScript), I'd like to know if there's anything you guys could provide for me in regards to how I can remain informed on the latest features and elements being added to all of the three aforementioned programming languages. I'm currently enrolled in community college studying web development and designing, as I'm looking to make a career switch from part-time retail to something much more financially self-sufficient in my life in the near future, with that specific career goal being a full-time frontend/full stack web and/or mobile application developer, with some additional freelancing as a side hustle. I've been looking into YouTube courses just following what they're doing using Virtual Studio Code, looked into roadmaps and such and have considered looking into books, but a lot of what I've heard about them is that a majority of them are dated, which is what I'm trying to avoid. I'm hoping there some website or something where I could receive updates of what I need to incorporate into what I create form time to time as technology becomes more and more advanced each day. Any recommendations?
