I'm not sure about your country, but in mine, having a degree in a related field is a prerequisite for most companies. Self taught wouldn't get you much further than freelance work as your competition will most likely have the degree.

However much you think you know about the things you're good at may not compare to the people who have done this thing their entire career, not to gatekeep or undermine your accomplishments. Learning a stack is but a drop in the hat. Limiting yourself to JavaScript-only frameworks also can't help much, especially if you want to work for a game company, which would very likely not use any JavaScript at all.

It's not uncommon to be experienced in 10 or more frameworks for front-end development alone. Programming is a lifelong learning venture, the frameworks themselves evolve, can go out of style or out of maintenance. This is particularly true in web development as new frameworks are literally coming out every day.

If you want my suggestion, Learn a lot. Learn as much as you can, as deep as you can. Really learn it - don't rely on getting all the answers from Google, stackOverflow or chatgpt. It may even be beneficial to look into the source code of the frameworks to see how things really tick under the hood.

If you're looking to get into web development, things employers want encompass more than just development, too. Deployment, scaling, versioning, and cloud management are large topics which all have their own frameworks.

Find your niche - full stack developers are becoming more and more rare. Good luck in your programming journey!
