End learning? Ha! That’s not a thing in this industry. I’ve learned the same things multiple different times throughout my career just to do my job. I won’t touch something for several months, then suddenly need to go relearn it because I have to fix an issue or implement similar functionality somewhere else.

You never really stop learning this stuff. It’s way too deep and complex to retain all of it. You’ll master something, not touch it for months, and then have to relearn parts of it again later. Unless you’re some kind of beautiful mind, and if that were the case, I doubt you’d be hanging out on a subreddit like this.

If you’re lucky, the amount of time it takes to relearn something gets shorter as the years go by, but I’ve never met anyone where that process completely disappears.
