Its pretty annoying, for almost a decade all js questions have j query solutions, if you ask for that in reactjs or god forbid, vanilla js, which also went through many api changes, its still a duplicate.
Often itscthe same for css, where grid and flexbox are now standards, the old questions with replies full of vendor prefixes and very hacky solutions should be deprecated or transferred to archives.
Btw, how do the blog posts copying so questuons monetize and how does google not shut them down, the pages dont even work, I thought google would know better?
