Oh yeah all the time. Its what taught me to RTFM because in higher languages like JS or Python there typically already is a built-in function to manipulate basic types like arrays and strings, so my goal is usually to exhaust the API reference for a certain object and google around before committing to writing my own for-loop to iterate over an array.
But props on your code! It is very legible which is always the best place to start at before optimizing. Write legible code and when you’re sure there are no more features you need to add then start optimizing.
That’s the neat part, you don’t! Don’t have to remember shit, just look it up again.
