Totally agree with the other response. This absolutely was not standard before class syntax was introduced. Use of constructors, new, this, etc. was the standard - class was essentially just a back port, adding syntactic sugar on top of the prototype design that was inherent to JS from the beginning. The only time I saw something like this was just from people that didn't really "get" or understand inheritance or OOP.
