Basically, title. This course is from 2015 and though I think every web developer at some point should definitely familiarize themselves with how pre-ES6 Javascript works, it is probably a bad idea to use this information as a starting point in your Javascript journey in 2022. Through this course, Mr Chaykin postulates many things, that is not correct anymore. So I dare to propose retiring his course from our curriculum completely in favour of some other, up-to-date material. For example, respective chapters from The Odin Project could be a good alternative.
