Using a tool that turns ambiguous cases into errors (as
@StandardJS does) does not suffer from the memorization problem, as long as programmers using the tool keep it up to date with any new syntax they wish to use.Show this thread -
But to be clear: memorizing the handful of rules that mitigated ASI in ES5 is no longer a viable way to avoid mistakes (and many existing blog posts describing this mitigation are already out of date as of ES6).

If you (personally) have thought a lot about ASI and have a good reason to believe you're safe (for example you use a linting tool that you keep up to date), TC39 has decided to keep it working, even in class bodies. But as general advice, people should default to semicolons.
