Ideally, you need at least some basic understanding to use the vast majority of languages. The problem isn’t even writing the code itself, you can definitely just memorize the keywords and some basic concepts and have at it. If you ask me, the real issue is the availability, amount and overall quality of documentation and learning material if you go about it that way.

I have a few coworkers who skipped the learning English part and learned most everything from other non native speakers and they tend to be crippled by often not really being able to make use of official documentation or keep up with new things, since the vast majority of content out there is in English. It also has the unfortunate side effect of pushing them to stick with whatever it is they learned way back when and not really looking for better ways of getting things done.

So basically, you can pull it off without knowing English but it’s going to be suboptimal and/or painful IMO.
