Ask Experienced Devs

Practice practice practice, always challenge and improve on your foundational skills. Everything else gets easier. Write code and solve problems, struggle through it in whatever way works for you. There's not really a shortcut to getting more experience than to put in the work.

It's especially important to try and do things the "right way" as a learning/growth tool. It will take longer, and you'll rewrite your code multiple times, but the next time you encounter a similar problem you suddenly know exactly what to do and the constraints around the problem.

Do this often enough and you'll find yourself having a general idea of how to solve just about any problem you come across, and how to do it elegantly.
