Constructors in JavaScript objects

Question

Can JavaScript classes/objects have constructors? How are they created?

Answer 1

So what is the point of "constructor" property? Cannot figure out where it could be useful, any ideas?

The point of the constructor property is to provide some way of pretending JavaScript has classes. One of the things you cannot usefully do is change an object's constructor after it's been created. It's complicated.

I wrote a fairly comprehensive piece on it a few years ago: http://joost.zeekat.nl/constructors-considered-mildly-confusing.html
