[COMPARISON] Watched a few hours of coding videos…. I have a lot to ask.

I watched a few hours of videos on coding, including Codecademy Pro, Udemy, Pluralsight, and Coding 101.<br><br>I believe the question I have applies to just about every field, but I will put this in here since it has to do with coding. <br><br>I have a question that can be applied to just about any job or career, but I want to know that after spending a few years learning and becoming a pretty good coder, is there a point that you get to where you feel like you can completely *ignore* everything that currently exists in the field, and be able to discover it all on your own at your current level and pace?<br><br>Put another way, is there a point where all *,\*\*existing\*\*** information that is available to you to learn at your current level and pace, where you feel like you can just \*\*ignore\*\* all of that, and figure out everything yourself, because you know enough that you can do that? <br><br>,\*\*Example\*\*: Anybody who is pretty *good* at Java and coding in general, for example, can either just look at the documentation for,\*\* `System.out.println()`\*\* and read what is there, or they could *ignore* that and just experiment with *different* print statements that aren’t \*\*listed\*\*, and do so by using their current working knowledge of Java, and just figure it all out on their own…. Anybody,\*\* can\*\* clearly do this, *,\*\*but\*\* at what level does this become \*\*efficient\*\*? <br><br>,\*\*Another\*\* example: Anybody who is pretty good at algorithms can either just go out there and read a lot about *different\*\*,\*\* known\*\* algorithms *,\*\*or\*\* they could use their current knowledge to just experiment with *different\*\* methods, and figure out for themselves whether or not it works, using their own methods instead of looking at established ones. <br><br>\*\*,\*\*Example\*\*: Anybody who is pretty good at coding can use a JSLint *,\*\*or\*\* *not,\*\* and just use their knowledge of *what \_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\,\_\?\_\,\_\_?<br><br>,\*\*You\*\* do have to start somewhere, *,\*\*but\*\* at some point, *,\*\*is\*\* there a *line\*\* or *point\*\* where you,\*\*,\*\* as you\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_?
