In my view this, prototypal inheritance, constructors, and most of "classical" OO in Javascript is simply better avoided when designing new JS code. I much prefer a more FP (functional programming) style approach. Use objects, but just put data in those objects, then write functions that take in those objects as arguments and do something with them.
I know that almost every introduction about Javascript starts talking about this and about prototypal inheritance, but IMO it's a load of historical baggage that's confusing and almost always unnecessary. Just look at contemporary React (with function based components and with hooks, but without classes) and you can see that we don't really need classical OO, "this" and prototypal inheritance.
(use functional components and hooks in React and you'll almost never have to write "this")
Plain objects and functions get you there 90% of the time, prototypal inheritance is historical baggage. Javascript (especially ES6 with arrow functions, destructuring and so on) is a cool language, simply don't use its legacy features, that's all just cruft.

We're a place where coders share, stay up-to-date and grow their careers.
