A lot of this article is background—it only really starts talking about class static blocks two thirds of the way through! If you’re familiar with the situation up to class fields (the last part of which, private class fields, has only landed in Firefox and Safari in the last few months), then you can skip to that point, the “Class static blocks” heading. If you’re familiar with ES6 classes but not class fields, then you can skip the first half of the article and start at the “Public class fields” heading.
