Thanks in advance.
Google (searching in general) never vanishes from your coding live so it’s good that you’re getting the hang on “how to search” when stuck ^^.
If you intend on focusing in web development specifically you would be well set if you also understand bootstrap so continuing the studies would be a good idea. For back end development it becomes less of a requirement.
You can check the developer roadmap guideline if you ever feel “stuck” on what your next step can be depending on what path you feel like following.
Regardless you can continue to do your own projects actively so you keep the knowledge fresh or do challenges in leetcode or similar websites so you practice both problem solving and your JS.
If it helps tell us which parts you feel less comfortable with so maybe me or anyone else here in the forum can redirect you to some content that you can study or practice actively to solidify that knowledge.
