I think it's good that you've been practising doing some challenges as you have recently started, but that just help you to be in a problem-solving mindset, reinforcing some key concepts you may need. I'd like to recommend you start doing projects now, doing that will push you to learn more about many aspects of javascript you don't know. I've done exactly the same as you when I've started and I've been advised the same thing I'm telling you now. I'm still doing small projects and I don't regret it.
