Prototype-Based. Prototype-based means that JavaScript is an object-oriented
programming language that can use items called objects. However, the objects
are not class-based, so no distinction is made between a class and an instance;
instead, objects inherit from other objects via the prototype property. You'll learn
how to work with JavaScript objects in Chapter 8. You don't need to understand
them in detail until you know a few other features of the language.

For those familiar with JavaScript, this functionality is comparable to using a
builtin class prototype object to augment the class. (Thanks to reader Erik
Eldridge for pointing this out.) 16. You don't have to know what each class in this
hierarchy does. I don't know what they all do, and I've been programming in Ruby
on Rails since 2005. This means either that (a) I'm grossly incompetent or (b) you
can be a skilled Rails developer without knowing all its innards. I hope for both
our sakes ...

The square depicted doesn't partially exist as part of the polygon depicted -
clearly they are separate objects. It's just that the features of the more general
polygon contribute to the features of the square. Sometimes you look or sound

you can say squares inherit from rectangles. Squares are also the derived thing
and rectangles are the base thing. Alternatively, squares are the child thing and
rectangles the ...

When used with the new operator, on the other hand, the function becomes an
object constructor and effectively defines a class as we know in object-oriented
programming. For example: ... As Marijn points out, using new with a constructor
function like this has a nice side effect that assigns the object's constructor
property with the constructor function itself. This is not true ... Personally, I also
like to avoid messing with prototype because you can really hurt yourself if you're
not careful.
