Good news! You have access to an awesome array of resources for learning Javascript. Here are the ones I would go with if I were starting in 2020.
The two courses I recommend if you like learning from books and written tutorials:
⭐️ The Modern Javascript Tutorial- https://javascript.info/
⭐️ Eloquent Javascript- https://eloquentjavascript.net/
If you're more into video:
⭐️ Beginner Javascript (by Wes Bos)- https://www.beginnerjavascript.com/
