I'm not sure that principle applies well to JavaScript. It was popular almost from the get-go, being the only language of the Web. A lot of bad practises were popular in the early days. JavaScript has changed a lot as a language over time -- ECMAScript 2019 makes it a lot easier to write good code than the original JavaScript. It's now better understood how to write JavaScript code, and how not to.
