That's how I learned. I'm a self taught dev so I pretty much just took the same approach. Read documentation, try it out, read more docs, try it out, read some examples, search for how other people do it, etc. At a certain point, you just know it and can solve 90% of your needs without looking at docs. Although, tbh, I haven't written a very complicated regex in probably a decade and would need to do some warm up reps if I needed to today.
