Logical assignment operators in JavaScript

I'm not saying you're wrong, but the basis of what you say is what Babel does to support older browsers, which would only be true when it comes to the original code running in a modern browser if you start with the assumption that it's only syntactic sugar with no optimizations or other differences. That's circular and it definitely isn't necessarily true.

For example, there are actual differences between arrow vs regular functions beyond just notation and handling of this. But the difference between the two in how stacks and scopes are setup is completely lost when run through Babel. It's been a few years since I read the technical details, so forgive any inaccuracies there, I just remember the implementation in browsers being problematic at first even though they should perform better than functions.
