Hi Ashley
I thing you can start with the basic with this site, its FreeCodeCamp, there will help you a lot in your own time.
Next step when you have the basic and understand Javascript you need to start make small projects and making more and more big projects.
Then only then start learn librarys i recommend for you ReactJs for front end (UI) and NodeJS Back End.
If you like something more diferent of Javascript, you can try Angular its in TypeScript, this its more easy for people coming from Java, C, C#, C++ and other similar super typed languages.
i recommend use FreeCodeCamp for start, and later if have chance buy some tutorials in Udemy are cheaper and help more if you have the basic understand, no before.
See ya.
