First, make sure it’s actually legal to get a job at your age. Many companies wont hire anyone until they are 18. Many more will only hire those with a few years of experience (from school or otherwise).
Getting an internship, where you can learn more, might be more reasonable, but do check the laws in your area.
Next, there is of course the “long term view” of investing in yourself. The single best investment is actually going to higher education for this stuff. There, you will learn more skills, and gain access to resources that are designed to directly lead you into companies doing this sort of stuff.
Practical skills are important, but they aren’t everything. A holistic, general approach usually helps the most in the long-term.
However, this is obviously only an option if available. If you don’t have the time or money to commit to such approaches, there are alternates, but the become vastly more risky and stressful.
The quickest way out/away from tutorial hell is to not use a tutorial at all. Tutorials will show you what you can learn, and general ideas of what you can do. But they wont show you everything, nor can they. They wont show you all the possible ways you can screw things up, nor can they show you how to fix all those ways. Those issues, and problems you run into are what experiences is made up of. The only way to get that experience, is to jump in.
With that said, if you know HTML and JS (and I assume CSS?) then look to combine those to build something using those. If you don’t know what you can build, I’d google around, but I’d consider knowing the limitations of what you know just as important as actually knowing.
It’s one thing to try to know everything, its another to know what you know and don’t know. With that context, you can go out and learn more of that “don’t know” stuff.
Knowing how to combine what you’ve learned to build stuff should be done often, and continuously. There’s always more to learn, but you want to make sure you know how to put into practice what you’ve already learned.
Regardless of what sort of future you’re looking into, keep up the good work, have fun, keep building keep learning
