Seems like a less than efficient way to learn and remember a programming language. Unlike natural languages, we can write programs with programming languages. We can run these programs, and if they still work, then they're probably still correct*. You can't do that with written/natural language.

As far as remembering programming language constructs and vocabulary, the way to do it is do projects. You use what you learned, and naturally, you're going to come back to it when you have to fix a bug or implement a new feature. All the while, you're building something good, too.

Another thing. If you're using a well-designed language, the concepts will incrementally build on themselves. They won't just be a bucket of orthogonal concepts, (like PHP, which seems to be mentioned in the article). Therefore, by learning fundamentals, you can more easily understand and decipher more advanced concepts. So, maybe you did forget what something does. But after a few minutes entering commands into a repl, you fully understand it again, because of your crystallized knowledge of other concepts.

I can't imagine a worse way to learn a new programming language than brute memorization.
