Started with JS, do I go back to HTML now?

Started off learning Javascript prior to FCC (barely started), and recently finished the entire Basic Javascript section. 100+ challenges.

Would it now be more beneficial to continue plugging away in the Javascript Algorithms And Data Structures Certification, or go back to the very beginning Responsive Web Design Certification?

Thank you. Newbie here looking for the best way to learn. Even the basic section I had to look up many answers and sit there perplexed until I could read through it and understand.

Well, if your aim is to be a web developer than you can’t really skip HTML and CSS. When you get a web dev job, you can’t expect that you will always do JS. You will have to write HTML and added styles to it. Also, you have to expect some basic front end questions in interviews.
