Every programmer needs to memorize the core of their language and framework. Sure, you can use documentation and IDE suggestions, but having plenty in your memory will make you much more productive, and if it need be the case that you need space repetition to memorize, then it's worth the effort.

I feel that using spaced repetition is counter-productive to learning a language / framework, meaning that using it would be worse than not using it. That is directly counter to the article's argument, though I'll admit to not having actually read it.

But even if it wasn't, then the time trying to memorize things would assuredly be better spent solving problems using whatever recall you already have and referring to the documentation when you come up short.
