I hear this sentiment pretty often but don't really get it. New features like async/await and Promises are added so that we don't have to do things the old/bad/confusing way any more - isn't that a good thing? Tools like linters and Typescript make it much easier to avoid the various 'old fuck-ups' and 'weird behavior'.
